Sound quality is great, found some interesting music. Recommendations are a bit of a crapshoot, but I don't necessarily mind that. Why no thumbs down option?

Sound quality is great, found some interesting music. Recommendations are a bit of a crapshoot, but I don't necessarily mind that. Why no thumbs down option? Might also be cool to see popular tracks or searches. edit - An indication of how many tracks are in your playlist in the top nav would be nice, and would also let people know that clicking "Like" adds a song to the playlist. Multiple playlists would also be useful.
