Just found out about Musicoin today in Poloniex Trollbox. Currency for musician and listener.
Before this there were Ujo on Ethereum which was one time experiment by Imogen Heap and LBRY which takes a noob a lot of time to learn and use. Musicoin is easy to use, just register using this Link. Once registered you get free 10 Musicoin and 5 more Musicoin for every invite.
Musicoin is the currency and the Blockchain that handles contract. The media files was told by the devs are hosted on IPFS (a peer-to-peer hypermedia protocol). The currency is mined using PoW(I guess) and can be traded at Bittrex.
IMHO its like Steemit with your profile on that one site, but the media is on IPFS. Its 0.00000850 BTC a minute ago in Bittrex, thats like $0.01, 10 Musicoin is like $0.10. Can give it try, who knows....;)
