Hi, I would really appreciate it if any one can help me: i switched from a PC to mac, so I burned all the music from my pc to cd's and then transferred them into itunes at the mac. But now what has happened is that all the information -title, singer, album title etc has disappeared, so it is all a mess. As well, a lot of the songs just don't want to play or they play for five seconds and then quit. I know now that I should have done it differently, but is all lost, is there anything I can do?
