Try having alook in the limewire folder which would be saved on your computer somewhere, prob in c drive under user programs, look for 'downloads' or 'my shared folder' or something like that, because i think the music gets saved to your computer aswell as the playlist on there

failing that go to start, search (right hand side of the menu) pictures, music and videos and should find any music on your pc (XP that is)

worth a try if you want your music from there
