I have to agree with Dom on this one. We don't see eye to eye on a lot of social issues but to me Bono is all bark and no bite. It's not like Bono is putting out a lot of top 20 hits. Only his real fans want to down load his new stuff. It is a punch in the gut to his fans not to allow them to do so without buying the entire CD.
From a business stand point, with so many music lovers having MP 3 players, it would make more since to make your money a buck 50 or so at a time. Seems to me you would actually make more money. I'm really not that educated about how the money is split, but I would think that Bono would get a decent cut of it.
