As far as I recall. YT Music pays even less than Spotify does unfortunately.
I believe YouTube music premium streams actually pay more than Spotify but the cross between YouTube paying way less and YouTube music paying more causes some confusion.
here’s a TL;DR summary for what we’ve got:
- Spotify paid the artists $0,0032 per stream
- Apple Music got the average rate of $0,0056
- Google Play Music landed a $0,0055 payout rate
- Deezer fell slightly lower at $0.00436

You cannot make a difference this way. Their music is a commodity they have signed agreements to sell. They probably (in the vast majority of instances) had almost no bargaining power in this and a lot of signed artists don’t make a penny from their work, at all.
If you really like an artist, contact them via their official channels and ask if you can send them money directly or donate to a charity they like.
