Hi @globocop ! Musicoin is an Ethereum fork, so it's mined with ethminer, Claymore, etc.
The 100 free plays is temporary, soon the system will be hardforked for free play, paid for by a 15% fee from mining.
Musicoin is ALL genres. No restrictions. My mix just happens to be hard dance music, but everything is already there.
Plagarism is policed just by the community right now. I imagine this approach will grow, as listeners and musicians are economically interested in the system, I don't think they will tolerate someone uploading a popular song under false pretense and draining the system.
