ITunes 11 Won't Let Me Add Songs To Library

Question

I made this a new question because the previous posts were pretty old. https://discussions.apple.com/thread/4562384?start=0&tstart=0 Thats the previous with the most replies that I could find. The options they suggested were :
1) file>add folder to library> navigated my way to the name of the folder> highlighted the one i wanted and pushed "select folder" and it brings in any song not already in the library.
2) Have you enabled the menu bar? with the menu bar enabled you can add file or add a folder, also at the bottom left you se the + sign, click that and you have the same options.
3) make sure ur genius is on.
That did my job..
4) I just selected "Copy files to iTunes Media folder when adding to library", it works! It was unselected before, and iTunes 11 keeps the old settings. If you are in the same case, don't miss this setting!
5) solved the problem by right-clicking the songs and clicking "convert to AAC". they immediately appeared in my library. hope this helps.
6) In store preferences, I deselected "Show iTunes in the Cloud purchases" and everything was back to normal!
7) I had this problem as well, what helped me was to rename the MP3 file you're trying to add and just try re-adding again. Hopefully it works.
8) Mine seems to work once and awhile randomly. If you look hard enough you can see the import crash. White box flashes up and goes away.
Sometimes clearing itunes cash/restarting makes it happy?
9)Problem Solved - If using Windows 7 and for instance you want to add folder to itunes you must first transfer the music you want to upload to itunes in the Music Folder - Noted as "Public Music Folder" - This applies to either music on your system itself or from an External Hard Drive - There is no other option thanks to the annoying Windows 7 Operating System - I transferred a huge file and then added it the usual way onto itunes and it worked.
10) Open iTunes.   Open Windows Explorer and locate the folder where your music resides.   Drag the folder of music into the iTunes window area where the albums are listed.   I just dragged it around in the iTunes window until the red circle with a slash turned into "+Copy".   Let go of the mouse.   The music is playing as I type!   Closed iTunes, reopened, it is still there!
So, now that thats out of the way, I went ot other sites and dont think any other options were given but if they were i tried them. Ive tried all of these things in different combinations too. Unlike some other people though, the songs never showed up in recently added and they wouldnt play when I clicked play using itunes. I've transfered music before for my parents from windows media player to Itunes when they got ipods and from one computers itunes to another. Can't figure out why I can't get this to work from this windows media player to new itunes. Its Not all the music though, only select songs, which seem to be the same as the songs in the SAME ALBUM that did work.

Answer 1

OK, I got the same problem, and tried all the solutions here, none of them works.
Then I tried everything by myself, and finally, I made it!
I just selected "Copy files to iTunes Media folder when adding to library", it works!
It was unselected before, and iTunes 11 keeps the old settings.
If you are in the same case, don't miss this setting!
