Q: CD downloaded music missin on itunes.

About a two years ago I downloaded every single song by Pink Floyd from all of their CDs. They were on my laptop for years, but I decided to upgrade. After downloading iTunes on my desktop I noticed that itunes didn't have a single Pink Floyd song for me to redownload. It is possible le for me to redownload them from the CD, however I left them with my father(because he is a big Pink Floyd fan too) who lives five hours away. Is there some kind of hidden folder these fongs would be in or do I just need to make the trip to grab the CDs?
