So after that post from Lena Raine about Qobuz, I think I'm gonna give them a try.
...it's also made me realize it's pretty dumb to be paying a distributor and only putting my stuff on Spotify.
I kinda like keeping all my projects in one or two places (mainly so I don't have to juggle several platforms), but it's probably not a good idea to put all my eggs in one basket when I'm still trying to build an audience.
TL;DR: expect the Frogsong OST on Qobuz and other services soon
