YouTube music being included effectively replaces an additional music streaming service. From that perspective the family oriented plans in particular carry a lot of value.
My gripe with Youtube Music is that the bitrate quality of their music is lower than Tidal or even Spotify. YTM audio files that are actually on Youtube will only stream in 128kbps.
I’m surprised to hear that. I just switched from Spotify to Youtube Music and found the audio quality to be way better, even though I had Spotify set to high.
