Slacker Radio

My friend Brandon recently recommended Slacker online radio as an alternative to Pandora. I find it a useful service, but I guess for now I still prefer Pandora. With Slacker, the service suggests similar artists based on your seed musicians. There is some good flexibility and options you can set, so I do like the service. But I think Pandora still has the advantage because it recommends and tailors the experience at the song-level, not the musician/group-level. At least, that is the way it seems to me based on my brief testing of Slacker. I'll probably stick with Pandora as my primary online radio service for now -- but I recommend to any readers that you give both a try!
