Let your fans become promoters for your music with your own Opus site.  Fans can create and share favorite photos using 10-40 second clips of your songs as the soundtrack in their OpusNotes.  Friends viewing these personal posts are exposed to your music along with links to your official site and where they can buy the song.  Every friend can then create and share their own OpusNotes, exposing your music to a new universe of potential fans, and the cycle continues.
