Whenever I see someone with an iPod I want to ask them, "What's in there?" I'm so intrigued by what people might be listening to. Podcasts? Books? What kind of music? (Right now for me, "And the band played on," by Simple Minds.)
I set up a playlist made up only of songs I've rated a 5 (nur fuenf). I can listen all day at work without hearing the same song twice. It's a beautiful thing.
