More important info:
Sony has an extensive (and ugly) EULA (End-user agreement) that says some nasty things now. I heard some ugly points summarized on TV that mentioned things like how it's technically illegal to listen to one of their CDs at work. Also - You are apparently supposed to destroy and delete any of the music if you declare bankruptcy at any point.
This is all decoded on the net somewhere. If I run across it I'll post it.
