Artists have told me to use Spotify because it pays best, so that's what I do. There's a reason why all the artists i listen to use Spotify as their main platform. Idk, you're gonna see a lot of different things online
The artists (usually) only see (or care about) the total amount they get paid from each of the streaming services. So...if Spotify has 3x as many listeners, artists are going to get paid more even if Spotify pays half of what other services pay.
But if Spotify loses subscribers because...for instance...other streaming services actually LISTEN to their paying customers...then those other services will pay more (overall) AND they will be able to increase the size of their catalog.
Same for me - Galaxy S10. Sometimes it pauses, sometime it doesn't. Same thing with my bluetooth headphones remote - sometimes the buttons work(play prevous, pause/start) and sonetimes I need to restart the app to make it work!
