Don't know, but I think it is not that difficult to monetize this user base - I think it is much more difficult to gain such user base in the first place. For starters, I would suggest to throw ideas, listed below, at the wall and see what will stick: 1. Kickstarter for albums [where funding is prepayment for goods/services] - taking into account the state of music industry this shall fly a long way. 2. Pro account - personalized pages for a band and sample tracks for a monthly fee, paid by a band. 3. Events organizer - bands can propose concerts for clubs, bars, etc. Making money - transactions - either as cut of concert cost (band-club) or as cut from tickets sold. And this feature is available only to Pro-account holders. I believe that just doing the above shall easily generate at least $10-50K per month in 3-6 mths, assuming correct execution. There are other options to monetize, but the above are the most obvious/simple to implement.
