I was updating my I-pod and I noticed that there is a whole library of songs that I lost when I switched computers. Most of the songs I lost I replaced but there's a large group I completely missed or didn't, depending on how you look at it. I have been using this computer since April or May and only recently realized that some of my songs are gone. I lost my whole Foo Fighters library. I thought it was strange that they weren't coming up and I hadn't heard them on my recent playlist. I was thinking, "Wow, I haven't heard any Foo lately." And then I discovered why. I guess that's the problem with having over 1000 songs.
