What is unclear is exactly how the new LimeWire will differ from existing NFT music platforms. Sound.xyz, which launched in December, explicitly focuses on common listening and commercial exploitation. Royal, run by producer Justin Blau, offers song royalties via crypto. The catalog is a marketplace for unique audio NFTs. And communities like Water & Music, Tiny Mix Tapes, Poolsuite, and Sone are experimenting with the social side of music NFTs.
