Mr Bojangles1 asked previously why it mentions video. Go to the YT Music app's settings and turn on the toggle for "Don't play music videos" and see if that helps.
No luck.. Not sure why it says video which leads me to believe this is a temporary bug on Google's part due a bad update. I'm gonna give a few days and am willing to bet it sorts itself out..
I'm just now having the same issue... did it start to work for you?
