Agreed. I am a massive fan of YouTube Premium and YouTube Music. While I am a bit nervous because major change like this could lead to those products getting worse, I'm also hopeful that it could lead to them getting better! So in general I'm just eager to see what happens next, come what may.
YT Premium, definitely yes. However, YT Music is hot garbage. The UI is utter crap and the mixing of video and music is awful, especially playlists. Why the hell would I want my regular YT and music playlists mixed up together anyway? It gets worse with kids, as some video-songs (randomly!) trigger the inability to play in the background.
