Have the devs considered allowing artists to sell MP3 downloads of their songs/albums in exchange for Musicoin? After the UBI fork it will become important to re-incentivize the purchase of Musicoin in some way, and many listeners would probably be willing to pay for digital copies of their favorite songs.
Yes, download contract is already in consideration after PPP for streaming. It's though a marginal demand for high-resolution audiophiles or collectors.
The contract to support download contract will be more flexible to enable artists to define price, instead of unified price in PPP contract.
