From what I’ve read (although my numbers are a few years old), Qobuz and Napster pay artists even more than Tidal. The former even significantly so (about 3x, from what I’ve read), although it is slightly more expensive. Both also support lossless audio.
And, for completion: Among the big-tech streaming services, the one that seems to pay the best is Apple Music, with a little more than half of what Tidal pays. The worst ones are amazon and Spotify which both pay about a third of Tidal.
They’re not the only ones anymore though. Apple, Amazon, Deezer, Qobuz and Napster also have lossless audio support.
