I use Rhapsody as my music player; what I normally do when creating a music list is I'll start with a song that I like and I'll use that as an anchor to build a list on. Sometimes I'll use the Mixer function to create a list; other times I'll look for a song or album that I like(Metallica's "Black" album comes to mind; that's the one with the coiled snake on the cover) and build a list off of that. I've got about 19 music lists there at the moment(when I was using Yahoo Music Jukebox, I had around 2 dozen or so lists)
