Yeah, since most of the public instances only make available creative commons stuff it’s better if you have a mood than particular artists. I suspect if most people switched they could find new artists to meet their tastes within a year.
My gut suspects that an artist with a good patron following probably has as much take home pay as a similar artist that signed a record deal. If true (and that’s definitely an if), why prop up up an industry that exists to siphon as much value away from artists as possible?
