Though Facebook is recieving most of the attention these days, MySpace remains dominant when it comes to musicians offering music and correspondence with fans.
To that end, the site has introduced a Music Artist Dashboard which promises to provide
global artists and labels with detailed analytics about their content within the MySpace community including charts, graphs, and snapshots. Data includes fan geography, song plays, profile views, friend count, and profile visitors.
You can find some more details here. If you've got a MySpace artist profile, you can check out the dashboard here.
