Any songs to remix out there?

I'm learning how to use Soundtrack Pro and would like to practice by remixing existing songs. I found a song by Nine Inch Nails they released in Garageband format. I couldn't find a way to open that file in STP, but fortunately I was able to pull out all the samples and loops. It's actually pretty interesting and it helps to see how the song was actually mixed and learn what can be done from that. Does anyone know of any other songs that have been released by anyone else like that?
