Rating of Songs

It would be a great feature if you could rate songs. That means you can rate a song from 0-10. Then you can see how you rated it yourself and how others have rated it, or what the average rating of the song is.

I would also change the popularity rating for a song to something else, namely "popularity," because that actually describes the point. A song can be popular and still not be good, or the other way around; there are also songs that aren't popular but are good.
