I dunno if they publish like a 10 TB torrent of the most popular music I can see people making their own music services. A 10 TB hard disk is easily affordable, and that's about 3 million songs which is way more than anyone could listen to in a lifetime, even if you reduce that by 100x to account for taste.
It's probably going to make the AI music generation problem worse anyway...
I would expect more data to make ai music generation better
