Young people are into a wider variety of music now than ever, as far as I can tell from having young relatives and only being maybe a decade or so out from "young" myself.

The progression of radio -> tapes -> CDs -> mp3s -> streaming services slowly but surely dramatically broadened things from the days of there just being a couple main genres. Mainstream radio hasn't kept up - the bandwidth isn't there - but there's a ton more out there beyond it.
