From those stats, looks like Spotify pay huge amount of their revenue to the labels - a lot more than UK radio stations do. (I am in UK - I am aware US radio airplay rules are weird in comparison).
If there's issues about songwriters / performers getting ripped off then looks like the issue is the labels (as presumably there's not a magic wand spotify et al can wave to hugely increase their revenue / what they pay out.
Disinterested observer as not a spotify, apple music etc user.
I still buy my music on CD or vinyl, as can then rip it and do what I want with it. Streaming of no interest to me - out in the sticks & phone signal often dodgy so need music to exist on device I am carrying as streaming unreliable. If I am not out and about, why would I stream as can listen to disks directly, or throw on the radio (still as good a way as any as expanding my musical awareness, though obviously UK radio plays very rarely figure up & coming "unknown" artists, but I'm not in the age demographic that needs to be in up with every latest new thing & OK for me to be "behind the curve" by a few months as there's so much music (& other media) that you can only ever consume a miniscule fraction of what is out there anyway)
