Like when some kind of voice or instrument teacher/expert reacts to and analyzes an artist's performance.

I don't look for them or anything but if the algorithm brings one to my attention I'll go down a rabbit hole for a bit.

It basically boils down to the fact that I (or in the case of a really popular song, people) already enjoy the music, and hearing experts break down *why* or *how* something is so well done is quite satisfying to me.

I have a little bit of theory and technique understanding from music instruction when I was younger, but that obv can only help but so much.

They account for a pretty small segment of the reaction video genre tho, from what I can tell lol
