Damn, I love the Internets.
Extra plus: Wolfgang says, "Based upon all the information that is available to us, we believe that performers can earn between four and six times more from Wolfgang’s Vault per download than they currently receive from their record companies. In a well publicized dispute between performers and major record labels, the performers state that they typically earn only $.045 per downloaded song – less than 5% of the total per song download price.
The Wolfgang’s Vault agreement pays the performer significantly more, remits the money much faster and gives the performer the tools to review download sales activity in real-time."
Good on you!
