A vast amount of people pay for Spotify, Apple Music, Youtube Premium etc, it's a huge market.

I wouldn't pay to have this played at events over live musicians. Is that better, mister redditor?

What do you mean? Access is one of the valuable things, not to mention the equipment the listening is done by is also usually bought.

Aside the online part which is massive on its right own - live performances/concerts/festivals, etc.
