I love the idea, but the reality is PRS and other collection societies need to work with this so as they have the tech to log all plays in effect you need to have the peertracks and muse meta data as well as the old data to hang togther, Its been awhile since I last took a look at peertracks and please we are getting a bit more info here.
As an anwer to another post here about promotion they old labels have stoped funding new acts and only want dead certs for money or X Factor rejects, take a look at bandcamp as this platform is starting to come of age and Juno Records we are starting to see real bands and DJs and people are connecting to them.
