Old School Runescape if you like grinding. But you might never quit if you get hooked :')

I have been very happy with desec.io, they are a nonprofit based in Berlin.

Jmp.chat is very cool. It is a $5 month subscription and gives you a US or Canadian phone number for texting and calling. The app it works best with, Cheogram, is also FOSS. I think it works with all XMPP/Jabber clients though. They will also host an Snikket instance for you with your subscription if you request it.

Thank you everyone for the helpful replies!

Nextcloud + Nextcloud Music App is also a good solution. The app supports subsonic too, so it can be used with a few different apps.

Very excited to try this out. Already have 70 hours on my deck. Supergiant Games is awesome!
