Via Alex Barnett's post, with the earning potential of these things I can think of nothing better than for some of the cash to go to charity! You can get more details on the Big Noise Music site, where I notice they have a 1p streaming thing as well as a 75p dowload service. They seem to have support from some big UK artists including Coldplay (predictably), Ash, Badly Drawn Boy and Melanie C (unfortunately) ;-).
