Earlier this month, AIM announced that iTunes, Spotify and Amazon account for 94.4% of the global digital revenues of its members. Now digital distributor INgrooves has taken issue with those stats, saying that the three services only account for 74.5% of total digital revenues flowing to its members. “We think it’s important to clarify the difference in the AIM report and our own numbers regarding indie digital revenues,” CEO Robb McDaniels tells Digital Music News. “Independent labels that expand their retail network will benefit from a significant advantage; they will see more revenue and more worldwide activity in the digital marketplace.” One explanation, of course, could be AIM’s heartland in the UK (although it’s a global organisation), versus INgrooves’ in North America, where Spotify is not yet available. Although whether that’s nearly 20 percentage points worth of difference is doubtful.
