Looks great, but the problem I see with these is they're all data-agnostic and centralised. We'd have to be able to decentralise it AND detect music somehow - whether that's by individuals listening and voting for and against, or automated metadata checking, a combination, or something else entirely...
Yeah. Difficult problem. You basically have to build out consensus networks outside from a basic ledger. Something like reality keys almost.

I reckon we first try to improve the economics of the coin, keep it simple, and keep the discussion going on how to incorporate music into a blockchain: either through consensus, or cryptographically. Both are hard, but we are breaking new ground here. Let's change the world!
