Can't delete songs from iPhone 4s

I found something that I think might work. For some reason, (maybe an iOS 5 issue) the 4s likes to hold information even if deleted from your iTunes. I made the mistake of renaming the folder that contains all my iTunes music/video files. Instead of finding all the locations, I thought it would just be easier to delete my library and reload the newly named folder. This screwed up the music app on my 4s beyond recognition, which, as I understand, is already an iOS 5 issue (ie: misorganized albums, artists, and songs). Well after several attempts of the unsync then resync method I realized that when I would unsync my library I would still have 10 gigs of music on my phone. Come to find out this was the music that was originally in my iTunes that the phone some how held on to. This would not show up under manually manage music and seemed unaccessable. After a little fiddling I found a solution. This may require you to delete all your music and start from scratch (I didnt play around with it too much. Just deleted all the music that was on there). Anyways, unsync your library. You should see that those songs are still alive and kicking in your library. go to "Settings", "General", "Usage". There it will show all your apps and how much data they are currently using. Find your music app, tap edit and delete it. Then just resync your library without those tracks and you should be good.

Dont give up faith man. iOS 5 is brand new. A few bugs are to be expected. Ice Cream Sandwich will have bugs of its own. Just keep an eye out for updates on iTunes and things will start running smoother.

Not sure if you ever sorted this out but the easy way to delete individual songs with iOS 5 is go to the song on the phone in the Music app and slide your finger to the right. A Delete button will show up and you just click that.

To delete an item from your library:

1. Click the item to select it, and press the Delete key.
2. Click Remove.
3. Do one of the following:
   • To remove the item only from your iTunes library, click Keep File.
   • To delete the item from your computer, click Move to Recycle Bin. The item is deleted the next time you empty the Recycle Bin.
