Some songs dont work, Random freezes, etc.

I get random freezes, some songs just flat out don't work when they do in itunes, unsure what to do, 5 R's dont do jack, along with anything else found on this site...i cant even find a ipod online support thing which is rediculous, any help is greatly appreciated.

well, i've done many things from switching the drive, a number of restores, and such. It's not JUST that the song doesn't work, it does this really werid thing that when its playing a song, it'll randomly reboot...then i'll replay that song that it just had a problem with and it'll work, until a few songs later and it happens again. One thing that i'm now trying it setting my ipod on shuffle, but this time locking the wheel to see if its an actual error with the wheel that for some reason its getting the impression that its being held down or something and causing it to reboot itself, I doubt it'll work, but hey! anything is worth a try at this rate...i'm also converting ALL of my songs to AAC then i'll sync them to the ipod and see how well that goes, if you or anyone else has any other suggestions, i'm open to them and appreciate them very much! thanks for the help so far!

  • When i download songs from i tunes to i pod some songs dont play or they skip songs or they make 2 copies of songs  what to do

    when i download songs from i tunes library to i pod  some songs dont play or they skip songs  or they make 2 copies of songs  what to do

    *Skipping songs*
    The iPod seems to fail to play all of the occasional track that iTunes, and indeed other PMPs, are happy to play. There is probably some minor technical error in the internal structure of the file which is normally ignored by other playback software but causes the Classic to bail out.
    You may like to try scanning the files with MP3 Validator which can find & fix some internal MP3 errors.
    Some users have also suggested that completely removing all id3 tags and then replacing the information can be a solution. This can be achieved in iTunes by selecting an affected track, right/option clicking and using the option Convert id3 tags > None. Since some files may mistakenly have more than one tag you may need to repeat this action. Once you have confirmed that no tag is present you can replace the tag information using Convert id3 tags > V2.3 (I believe it is recommended to avoid using V2.4).
    Personally I have found files for which these solutions don't work. In this case the workaround is either to re-rip the tracks or get iTunes to re-encode the file, e.g. convert AAC to MP3 or vice versa and sync the newly encoded file to the iPod instead. Because transcoding will cause a loss of fidelity you should keep your original file so that if a future iPod firmware resolves this issue you can put your original files back onto the iPod.

    Please describe in detail all you have attempted to do in order to resolve the issue.  Have you tried restarting your computer?

  • HT203167 I recently downloaded my previous purchased items from iTunes but I have found that some songs dont play or have only downloaded half of the actual song :/

    I recently downloaded my previous purchased items from iTunes but I have found that some songs dont play or have only downloaded half of the actual song :/ when i go to iTunes>Purchased it says that the songs have already been downloaded, which means i cant re-download them. is there a way I can re-download my previous purchased songs?

    Once you successfully add you iTunes library to iTunes Match, you go to Settings>iTunes & App Store on your iOS device and turn on iTunes Match.  Your iTunes Match library will then appear on your iOS device.

  • Some Object dont work after restoring it from the filesystem

    Hi !
    I have a JFrame and in this I have a JPanel.
    In the JPanel I have a JTabbedPane.
    If I store the JTabbedPane to the filesystem using ObjectOutputStream and than restore it by using the ObjectInputStream some JTextFields in the JTabbedPane dont work correct. The most Objects work okay.
    Do I have some problems with the pointer or is the reference lost ? I have 40 Objects and 2 or 3 are frozen after loading the JTabbedPane. Hmm...
    Some lines of the code:
    <code>
    // WRITE OBJECT
    if (e.getSource() == jMenuPosSpeichern)
    { try
    { ObjectOutputStream stream = new ObjectOutputStream(new FileOutputStream("c:\\test.dat"));
    stream.writeObject(jTabbedPane);
    stream.flush();
    stream.close();
    catch (IOException e9) {e9.printStackTrace();}
    // READ OBJECT
    if (e.getSource() == jMenuPosOeffnen)
    { try
    { ObjectInputStream stream = new ObjectInputStream(new FileInputStream("c:\\test.dat"));
    contentPane.remove(jTabbedPane);
    contentPane.repaint();
    jTabbedPane=(JTabbedPane)stream.readObject();
    stream.close();
    contentPane.add(jTabbedPane);
    catch (Exception e8) {e8.printStackTrace();}
    </code>

    No they are not different.
    On the first register of the JTabbedPane I have 2 JTextFields an one JComboBox. The first JTextField is frozen. After trying sometimes the second field is frozen.
    Is my way to store an object the correct way or is there a better way available ?
    The relevant fields have this line in the source.
    (code)
    ....class...
    JTextField name = new JTextField(30);
    ....constructor....
    jTabbedPane.addTab("register1",reg1);
    reg1.add(name);
    name.setBounds(170,100,200,20);
    (/code)
    All my fields I add to a Tab of a JTabbedPane and all the Field have setBounds. No difference to the other objects.
    Thx Wolfgang

  • Some songs dont appear in artist

    hey well i havent had any real troubles with my ipod until now. all thats happening is, i synch my ipod with itunes and it says all my songs are downloaded.. and then when i turn my ipod on, it doesnt show many of the songs in the artists, but shows them when i click ALL at the top.. or just SONGS. does anyone know what might be happening? its weird cause its like itunes is selecting which songs to put in artists or not...

    You should check that the songs have album name info in their ID tags.
    See: Some songs don't show under artist on my iPod.
    Once you add a second album name for that artist even for a single song, ALL the rest of the songs should now show up under that artist, even those without album names.

  • Itunes songs dont work

    Hi,
    I bought on itunes Justin Biebers new album and 6 songs from the album does not work on my iphone. They do work on computer in itunes but when I synchronise PC and Iphone the Itunes tells me that "6 itunes could not be synced. See itunes for more information".
    Does anybody know what could be the reason? Please help
    Merry Xmas!

    If your country's iTunes Store allows you to redownload purchased tracks, I'd delete your current copies of the dodgy tracks and try redownloading fresh copies. For instructions, see the following document:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store
    Otherwise, I'd report the problem to the iTunes Store.
    Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
    Find the items that are not playing properly. If you can't see "Report a Problem" next to the items, click the "Report a problem" button. Now click the "Report a Problem" links next to the items.

  • Safari and some websites dont work?

    Ok here, I sometimes want to visit a few websites that have people's profiles, such as the well known myspace. So when i enter myspace it seems to go fine untill i enter just a few people's profilesand then it looks like the page is loaded up, but it isn't, the little spin icon comes up and it just keeps going. Its not just with myspace though, there are a few pages i remember visiting that don't seem to want to come up. Please if anyone has experienced and fixed these problems please help me. Also maybe if someone knows how to use Spin Control to this advantage please tell me how to use it. Thank You

    Hi, Razvan, welcome to Apple's user-to-user discussion forums.
    Myspace is well known for horrible web design by its members. Safari is one of the least forgiving of browsers when it comes to bad code. You might want to try using Firefox for going to Myspace or other sites that Safari chokes on. Some sites are programmed using proprietary Windows-only technologies and you will have problems with those sites no matter what browser you use on a Mac.
    I have just randomly gone to various pages in Myspace using both Safari and Firefox and nothing has frozen up on me, but some pages took a long time to load in both browsers. I did not happen on some of the more extreme user pages I have seen, but I did get to some which were highly "creative".

  • TS1424 i purchased a album on itunes and the songs dont work

    i purchased a album from itunes and the songs wont work

    Delete the songs from your iTunes library and redownload them by clicking "Purchased", under Quick Links at the top right of the iTunes store.
    If this doesn't work contact iTunes support here:

  • Some photos dont work after importing from iPhoto 4?

    Hello,
    I recently upgraded from iPhoto 4 to iPhoto 6. I updated my library by copying the iLife 04 photo library to my new iMac. When I opened up iPhoto 6, it updated the library, and everything worked fine, or it seemed. All the pictures and thumbnails were there, but on around 1/3 of the pictures, I only have a thumbnail. If I click on the thumbnail, the picture never loads. On ones with a picture it loads very fast.
    Any ideas?
    I have the library backed up on DVD, so im not worried about losing the data, just want it to work.
    Thanks,
    Adam

    Adam:
    It may be an ownership/access problem. Manually set the ownership and access on the iPhoto Library folder as follows:
    Setting Permissions for iPhoto Library Folder
    1 - Select the iPhoto Library folder and type Command-I.
    2 - When the Info window comes up go to the Ownership and Permissions section and make sure You have Read & Write permission and that the Owner and Group have Read & Write also. Others - Read Only.
    3 - Then click on the "Apply to enclosed items..." button.
    See if that may help. If not try selecting one of the files in the Original folder and type Command-I to bring up the Info window. In that window set Preview as the default application and click on the Apply to all button. Good luck.

  • I downloaded an album and some songs dont play completly

    I bought an album on tunes
    On my Ipad and Iphone its ok
    But on my PC songs don't play completely  they stop  before the end of the song
    How can I fix that ????

    This happened to me.  What you need to do is move the song and any backups to the recycle bin.  Then go to Itunes store and click 'Purchased' under Quick Links.  Go to the song you want and there will be a cloud next to it.  Click it and it will redownload.  It should download the full song this time.
    This happened to me yesterday when I bought a Volbeat album and again today when my brother bought a Rise Against album.  I hope Apple fixes this.  I just read about a question like this from back in 2007, so it's been going on for a while.
