Trading songs on the blockchain sounds like a reasonable idea until you realize any MP3 player that would enforce ownership needs DRM now, which it must either enforce by downloading the blockchain periodically, or periodically talking to some untrustworthy music-industry server that purports to interpret the blockchain but could shut down instead.

Music and the arts are where I get worried, because I've seen a lot of good people get involved in NFTs.

The regime we had beforehand wasn't working. Spotify royalties were pathetic. The interest in Web3, among artists, comes more from fear for the future than techie opportunism.
