@vancha I don't know if any of the ones listed at https://fckdrm.com/ are built on open-source software, but they don't require clients.
@vancha Yeah. I actually discovered Jamendo through an open-source game that uses music by a band on it.
http://mars-game.sourceforge.net/ (`marsshooter` in the Ubuntu Universe repository)

It's sort of like a SoundCloud that doesn't fight tooth and nail to prevent downloading unless the uploader pays money.
@ssokolow hah, seriously? symphonic metal in a game? best combination ever :D
@vancha Oh, I almost forgot. I've gotten some excellent indie music from bundles on https://groupees.com/ over the years.
(For example, the albums containing https://www.youtube.com/watch?v=U5u9glfqDsc and https://www.youtube.com/watch?v=E52rxz2sjRs )
@ssokolow Hmm nothing really seems to pop up, but thanks for the suggestion nonetheless :) good to know there are at least some drm-less options.
