Mike Shinoda is a musician (formerly with Linkin Park) and he released a generative NFT for his rap mix tape [1].
You can listen to or view any of the NFTs online without restriction. Buyers of the tokens support Mike with Royalties on each sale, and in consideration holders have received a follow on airdrop. This is a connection between the fan and the artist. To answer your question, the buyers want to record that connection to the artist. What else emerges remains to be seen...
