Today I just released my take on personal music streaming. Some days ago "Phan An" released Koel (
https://github.com/phanan/koel) and made me smile because I already started a similar project time ago, however instead of ripping of Spotify UI, which I personally find terrible, I made a "power user" UI that is album-centric (they way I listen music to), keyboard navigable and has a powerful filtering "omnibar". Check it out, it is just one "npm install" away!
