Cool thing about Slacker is you can go to their website, log in, and customize channels by specifying a primary band, then choosing from the other 100 or so it thinks are similar. Go to your bb, update channels, then your custom channel shows and only songs from the bands you picked will play. Only disadvantages I've seen with Slacker vs Pandora is the app size is about 4 times greater and it seems much slower to load and start playing than Pandora.
