Bittunes
Description
"Bittunes is creating a social music sharing & earning web-service, Android app & P2P network, that monetizes the exchange of digital data as users share songs, initially exclusively using Bitcoin as the primary operational currency, but denominating all songs in $US. Bittunes deals directly with the Music Piracy problem, with a carrot not a stick, rewarding artists fairly, and allowing users to potentially earn 5-10x profits on song purchases."
