I only learned about Ed Sheeran not that long time ago, when I had a meeting with my student. And the student had to leave early because of Sheeran having a gig in the town, and I played like I know what youngsters listen to these days and was like “oh, wow, didn’t know System of a Down perform here tonight”. I tried to extrapolate to the name space I knew and Serj Tankian was quite close, lol. It was awkward.

The only one I know is Adele. I have heard of some of the other artists but can't say I have heard of those songs.

You aren't old yet but you are getting there.
