I think I would have preferred if they named fake artists instead of making dated and even outdated references to pop singers who are all garbage. I can't imagine anyone finding deep philosophical inspiration in... Ed Sheeran.
"You sure do listen to some serious stuff" is something you say to someone after you find out they listen to Ghost, or Arcturus, or fuck, even Master Boot Record or Blackbird Raum. It's not usually said in response to the most milquetoast top 10 radio hits singers like Ariana Grande or Rihanna.
