I like how you rate songs.

I don't like how you can only give something a score from 0 to 5 stars. No half stars equals only six points on the scale and considering two of those points are at the extremes it feels like you have even less options to pick. 

Anyways, that's an old complaint. My other pet peeve is the inability to rate entire albumbs. Sometimes I just want to see a listen to an album from a list of ones I like. It would be ideal to tag albums as 4-stars or 2-stars, etc.
