@CppGuy I know Dua Lipa because she was on Barbie. I know Billie Eilish because kid liked one of her songs and because people made parody memes.
Ava Max was in Barbie too (and so was Eilish, but I had already heard her), but she wasn't on this top list.
They're all great, and I've listened to them more since, but I wouldn't have known of them if they didn't reach me in some incidental way.
Taylor Swift is everywhere and impossible to have not heard about. She's even in the news, because men older than me aggressively don't like her for angry old man reasons.
But what I listen to most is Queen, Mike Oldfield and Daft Punk.
