Nice little statistic buried deep inside the Christian Science Monitor:
Tim O’Brien, head of business development at Tapulous pointed to a recent track by Katy Perry, the chart-topping American pop singer. More than 250,000 users [of iPhone app game Tap Tap Revenge] loaded “Hot N Cold,” Mr. O’Brien says, and of that number, 56,000 ended up purchasing the song from iTunes.
It's a nice little extra sale, on top of the modest fee for licensing the tune. With something making a small but unexpected profit, it's probably only going to be five minutes or so before label heads start to demand larger shares of revenue and/or issuing lawsuits.
