aggregate sorting suggestion
As arn said, its all about users' recommendations. Not only individuals though, but aggregate recommendations. As the site fills up with tons of users recommending tons of songs, i think we'll use the site in two ways -- asking it "what do people like?" and "what do people like me like?" Being able to do refined sorting of most-recommended material will be increasingly important for both types of questions.
It would be great to have the familiar interface of:
Genre>Artist>Album>Song
where you can sort by "most recommended" at any level there (and eventually have weighted recommendations by friends, etc, but that's maybe a ways off...).
so you could ask:
between genres: "what's the most popular (or most recommended) style of music?"
within a genre: "most popular hip hop music?"
within an artist: "most popular jonathan richman song?"
and within a song: "most popular version of 'my favorite things'?"
Great work - looking forward to using it more!
