In my experience Slacker seems to really like certain artists and tends to play their tunes a lot, even though you haven't specifically asked for them. One example I can provide is Bad Company. I have set up Artist stations for other Classic Rock artists like The Rolling Stones, Led Zeppelin, etc - but for some reason I get a lot of Bad Company's songs. The Doobie Brothers, The Doors and Steely Dan are other examples. Yet other artists are not played very often at all for some reason. I wonder if this is financially motivated? Does Slacker pay less per play for these "overliked" artists, compared to other artists.
