1. `npm i onchain-music-metadata`
2. `import "onchain-music-metadata/contracts/OnChainMusicMetadata.sol";`

contract MusicNFT is ERC721, ExampleToken {
uint256 songId;
constructor() ERC721("music nft", "mnft") {
songId = 0;
setupSongMetadata();
setupProjectMetadata();
}
function mint() public {
songId++;
_mint(msg.sender, songId);
}
function tokenURI(uint256 _tokenId)
public

override(ERC721)
returns (string memory)
{
require(_exists(_tokenId), "tokenId doesn't exist");
return musicTokenUri(_tokenId);
}
}
