I had gotten Youtube premium and enjoyed it. My subscription ran out and I find I have 90% use of it for free. I got it to listen to the app on my phone when I was out. However the app sucks ass. I would listen to one song and then the app would just crash. SO I never got to use it for the intended use.
So which would you choose? Youtube or Spotify? and how is the Spotify app on the phone?
Spotube, it uses your (free) Spotify account to get the Playlists and artist info etc, but then uses YouTube Music as source for playing the media. No ads.
