Just github. It doesn't seem like there is a way to actually grab the ogg stream from Spotify, but some hacky way of grabbing music from other sources, and they won't sound good.
I'm not sure why they'd do it the way they are, but I guess some people find it useful. You're probably better off just using the Spotify app, even though it's DRM for downloads.
Switch to Tidal and I can help out
embrace the MQA nonsense. You know you want to.
