I am mid-40s. My daughter is 11. I take her to school, among other driving things, and usually play NPR. Whenever she needs to refer to what she’s hearing – usually to ask if I’ll turn it off so she can pull up some godawful thing where a random Youtuber squawks discordant lyrics to a Pokémon video game score – she calls it a podcast. I’ve stopped correcting her, particularly since most of the “shows” release as podcasts by the next day anyway.
Embrace Greta Van Fleet.
Or don’t but there’s lots of good rock still being made if you put a bit of effort into looking for it.
