This site is free?! Audiophiles who want to discover new music, or simply don’t know what they are in the mood to listen to, would pay a lot for Musicovery.com. (And, indeed, the site has a premium membership that streams higher quality music). What’s so cool about Musicovery is the interface. Select the genre(s) you want to listen to and your mood from a matrix of energetic to calm, dark to positive, and your suggested song starts playing on a page with a a sort of flow chart to similar tunes. Give it a listen and try not to get addicted.
