Gee I wished there was a way apart from Google Play/Apple Music to have my music library uploaded somewhere and be able to play it back on a desktop app =_=
Apple Music requires iTunes, and iTunes is a disaster with the size of my library (~100GB / 13k tracks). And Google Play is owned by Google and there's officially no desktop apps and the ones that exist are only decent.
Right now I'm using Swinsian on Mac and Dopamine on Windows but that implies that I have my trusty external drive with me to play my music.
I've seen Tomahawk that should be able to play stuff from GPlay/network but the UI (at least on Mac) is god awful and nothing ever worked on my machine.
@Eramdam I like Ario as a GUI MPD client.
