I think UBI will unleash the beast on Musicoin. 20% of coins mined go tho the UBI pool. Musicians get paid a flat rate of $0.02 per play equivalent in $MUSIC.

The more the plays, the more the coin becomes scarce in the UBI pool --> The higher the price of the coin.

The only thing that needs to happen is either a big artist comes over bringing his/her listeners. Or indie artists attract enough listeners, which in turn will make some noise, attracting some big artist. One's gotta give.
