Same result here, never heard about karol G and Charli XCX but to be fair, I find most modern pop music to be very manufactured and boring. People like Max Martin can create a lot of hits but it makes the music rather uninteresting.

Just listened to Brat from Charli XCX and yeah, not missing much.

I feel that when it comes to Music, being in sync with pop music is more of a generation thing.

On the other hand, I wouldn't describe myself as lonely... I'm not super social (I've worked remotely for 13 years because I don't particularly like working in an office) but I do meet up with friends 2 times a week (used to be more but with a kid at home, there's less time).
