Put off by my shift away from curating my own music collection and relying too much on Spotify for their fancy Connect functionality to switch between devices/speaker setups, I sought a new solution

BOOM, SUBSONIC BABY!! Streaming from my PC on any device, chromecast button, I can switch where it's playing, multiple people can even contribute to a queue from their own device too

UI's a little rough/dated feeling but I think there are alternative clients you can run anyway!
