Pandora never worked for me.
Started with a song, it switched to something I liked, it then switched to something I didn't like, it then switched to something I didn't like at all, it then switched to something horrible, and got worse, and worse. As often as I tried, it only moved away from what style I originally wanted. It's frustrating to start out with RHCP - Can't Stop and end up with Britney Spears after 20 bad songs...
Maybe it's because I don't identify with bands, but certain songs. i.e. I like some RHCP songs, but don't like others. Perhaps it gets confused with that.
