Puts a lot of burden on the consumer. Background checks; does this artist the potential to deliver good music again? Does the album's concept sound good? Which of the dozens of artists I know are asking for funding? (Not even to think about discovery) Also brings us back to the model of paying for a whole album rather than just the good parts of it.

I have backed exactly one kickstarter project (I think $50) and it was more email friction than all my iTunes purchases combined (maybe $1000?).
