My understanding is MPIX owns the music licensing rights.... which means they can legally make money off the tracks in their library. They can create CDs, sell music on-line, sell temporary rights for media use, etc.
Several organizations have licensing rights. It's like Subway owners that have rights to use the name, 'Subway.' They have to send some of the revenue back to the corporate office (the 'owner' of the fast food chain).
So the money for the Chuck Berry song you heard on NBC was probably directly paid to Warner Music, Capitol records, or whoever 'owns' that song. OR it could have gone to someone else that owns the licensing rights... but the parent (owner) of the music will always get a piece of the action.
Diante spoke of a deal that is already on its path of success. We have no idea what that deal is, but if someone like Diante that knows how the music industry works is at the helm, I have confidence. Personally, I'd like to hear the news of this music deal he spoke of. Then it's blast off time!!! Go MPIX!
