Well my brother showed me this a while back. Its basically a simpler version of Pandora, except instead of picking an artist or song title, you pick a genre. Then based on the "mood" your feeling, it will generate a random song in that genre. Its pretty dope, and useful if you want to find new bands. And i don't think this has been posted before, checked the searchbar.
