I seem to have deleted a huge portion of my iTunes library from my computer. Don't ask me how as I don't have a clue. I have synced the iPod and most of the songs barring about 30 seem to be on the iPod but about 200 are not available to play on iTunes- it just says they can't be located. Most I have on disc so it's not a massive problem but i don't want to have to upload again. Is there anything I can do?
