Oh god, I've got 6,000 songs on mine, so I'm not even going to try and list everything. I bought an 80GB model so I'd never have to move things on and off of it; I can just keep filling it up. The vast majority is full albums, though. Everything is meticulously labeled and organized: correct tracklist order, correct spelling, album artwork, and so on.
