How can I add songs to itunes music folder without them being duplicated within the folder (not on my hard drive)?

Question

I have music files all over the place and want to put them all in itunes with no duplicates and get rid of all the rest. how can I do that? Some of my playlists are missing songs. I would like to move the playlist back to itunes from my ipod without having to put the songs in my media folder yet again! I have wasted so much time fooling with this. Really what I am trying to get at through all of this is to run the songs on the ipod through ivolume so they play equally.
Can anyone make sense of this for me?

Answer 1

It sounds like you have a few different problems.
To find all your music, try using a spotlight search. Type "kind:music" in the spotlight search (the magnifying glass in the far upper-right corner ) then choose "show all in finder". You'll end up with a window that shows all your music files, regardless of where they are on your hard drive. But don't move any files, because that may confuse iTunes (it won't be able to find files that you move, because - d'oh! - you moved them and now they're not where iTunes left them. That's usually how people end up in the kind of situation that you're in.)
If you want to let iTunes organize your music for you, make sure those options are turned on in the iTunes preferences (in the "advanced" section), then go to the "File" menu, choose "Library" and then choose "Organize library". That will put all your music in the iTunes Library folder (but leave copies of the originals wherever they were, all over your hard drive).
To find duplicates in your iTunes Library, choose "display duplicates" (or hold down the option key and it changes to "display exact duplicates" which might help in some cases). You'll still have to manually go through them to delete one of each duplicate.
Now you can start combining those three techniques - if you consolidate your music and let iTunes copy everything into the music folder, you'll know that iTunes safely has a copy of all your music in the iTunes Library folder. So you can do the spotlight search, and delete any duplicate files that are not in your iTunes library folder. Anything that's left over (that is, it's not a duplicate and it's not in the itunes music folder), you'll need to add to iTunes (try using the "automatically add to itunes" folder - spotlight search to find it -  anything you drop in there will get added to iTunes without leaving a duplicate file). Then you can use the itunes "duplicates" feature to find the duplicates in iTunes and fix those.
