Do you know how to get your music on Spotify?

Just in case you thought it was impossible to get your tunes on Spotify, it's not.
You can get your tunes on Spotify, even as an un-signed artist very similar to how you
would get music on itunes, through an "Artist aggregator."

Spotify shows you here:
