MUSIC NFT SMART CONTACT

To allow users to turn music files into NFTs, we can create a smart contract that manages the creation and ownership of music NFTs. Here is an example of such a contract, which includes advanced functions to make the platform a good business:

This smart contract includes several advanced functions to make the platform a good business:

The createMusicNFT function allows users to create a new music NFT by specifying a unique token ID, metadata, title, audio file hash, and price.

The function checks to ensure that the given token ID is not already in use, that the metadata and audio file hash are valid IPFS hashes, and that the price is greater than 0. It then creates the NFT and assigns it to the message sender, sets the metadata, title, and audio file hash for the NFT, and sets the artist address and price for the NFT.

The purchaseMusicNFT function allows users to purchase a music NFT by specifying a token ID. The function checks to ensure that the given token ID is valid and owned by a different address, that the message value is equal to the price of the NFT, and transfers the payment from the message sender to the artist. It then transfers ownership of the NFT to the message sender.

• The getMusicNFTSbyArtist function allows users to retrieve all music NFTs created by a given artist address. It iterates through all token IDs and adds those that are owned by the given artist address to an array, which it then returns.
• The changeMusicOwnership function allows users to change the ownership of a music NFT by specifying a token ID and a new owner address. The function checks to ensure that the given token ID is valid and owned by the message sender, and then transfers ownership of the NFT to the new owner.

These functions, along with the use of an ERC-20 token for payments, allow for a robust and successful platform for creating and selling music NFTs.
