YOU CAN GET YOUR MUSIC BACK. The same thing happened to me. If you've got all ur music on ur iPod theirs a way to get all ur music back on ur computer.

1. Plug in ur ipod

2. iTunes will open but dont press anything thats pops up because u could delete your whole libary of ur iPod

3. Go into my computer one of the drives will be ur iPod

4. In the drive their will be a folder called ipod_control(you need to show hidden folders)

5. Open it and inside it their will be a folder called music open it and their will be lots
of folders with these folders contain ur music but they r all called XFGY and DEFG ect.
but when you put them in iTunes they go back to their proper names

6. Copy all these files into a folder on ur harddrive and import them into iTunes
