I use Youtube Vanced on my phone so I basically have potentially free Youtube Music.
but I pay for and Use spotify with a family plan that I have my wife and our best friends all on, so we can share playlists and stuff.
While I dont like how spotifty pays the artists and all that jazz. the features like the release radar make the service worth it. and the more it gets to know your tastes the better spotify playlists made for you become.
