How it works?

The ProtoSound contract allows users to create songs setting a price and minting 3 types of tokens, an AuthorSongCover Soulbound token, an AuthorSongAudio Soulbound token, and a collection of SongCover NFT tokens.

When another user wants to buy and consume a song, after paying the price, one of the mentioned SongCover tokens are randomly selected from the collection and transferred to the buyer. Aquiring a new NFT token plus the song itself.
