You find categorize your music by genre?

I just seen a video that said “I don’t trust you if you have your playlists categorized by genre”. What??? That’s not normal? Apparently it’s a very weird, wild concept to some people. But I literally can’t listen to a bunch of different types of songs right after the other. I have to be in a certain mood to listen to a certain kind of music. It honestly blows my mind that people can go from country to pop to grunge to whatever the hell else. I just don’t get it. I literally can’t. Do you categorize your music? Or am I insane?
