itunes files are missing from me =(

I have a suggestion. Use programs such as Frostwire or Limewire, but make sure you have a good anti-virus/firewall, and scan anything you download. I have over 5,300 songs from downloading over the years. Completely free and somewhat very illegal - but the good news is that it works like a charm. You can easily search music by genre, artist, album, song name and some other options. SFJ had a good idea there, and I've never used iTunes myself but if the songs are physically on your PC (not sure if they stream from their servers?) you can just toss them on a flash drive or data disc and run with it.
