Social Music Gaming Communities

JamLegend

Jam Legend is a social music gaming website that is the place to "play" music online. Like Guitar Hero and Rock Band they have created an engaging way for artists to market themselves online. Unlike those games, their site does not limit the number of artists, songs or genres available on the platform, can host tournaments where hundreds of users can engage with music, and provide widgets and link to your websites and integrate your social networks (coming soon).  They claim that artists that submit their music have more plays then their MySpace site. It's free to sign up. 

thesixtyone

thesixtyone makes music culture more democratic: artists upload their work for review, but, rather than allow a stuffy suit in a boardroom to decide what's good, thousands of listeners do. The best music automagically bubbles up on our homepage where you can listen to the most popular songs for any genre. It's a quick way to find new music for your iPod powered by pure excitement as opposed to some contrived marketing budget. Listeners earn a reputation, level up their influence, and collect badges for discovering and recommending good music that others may enjoy. On thesixtyone, tastemaking becomes fun, competitive, and trackable. An average person spends 9 hours a week on the site. The listener split is 50/50 men/woman and their base is more college aged listeners. Listeners can either buy music from artists or give them a tip from .20 cents to as much as you want. It's free to sing up as listener and artist.
