Musicians can monetize their content with MusicArt
MusicArt is located at https://musicart.io and its creators are describing it as:
"MusicArt is the easiest way for musicians to get music into WEB3"
If I've understood MusicArt correctly, it makes musicians' songs into NFTs. They can then be bought and sold on that platform. I think the artist can decide how many copies of a song are "minted" -- it can be for example 100 or 500 copies. Looks like the most valuable/desirable copies are the first ones. For example "Hurt My Heart (Remix)" by Vocalizer has 500 copies, but the first and second copy got taken first. ;-)
