It might work better with karma (and games) instead of money.

All those accounting figures seem out of place with cool new music... but I don't know the profiles of indie music lovers - maybe they like numbers :)

EDIT I think startup founders (myself included) are comfortable reasoning in financial terms - but many people don't, and don't want to. They can even be offended and upset by it. I think this startup might need to find a niche market that is comfortable with it.

It might be better to disguise/hide the money somehow (but that defeats the pitch)... or, possibly extend the underlying microtransaction technology to other subject matter that is already financial oriented (or, has a financially-oriented audience).

These are just my opinions. What works, works.
