It's been a long while since I used it heavily, but there's Mopidy. It has plugins for quite a wide range of services. Mopidy itself is headless but has a lot of options of webapps & apps to control it. I had a great experince for mamy years doing whole house audio with spotify, google music, and lots of shoutcast/icecast via mopidy. Used it for my car audio for a while too.
