As much as I hate the way that streaming services like Spotify pay so little to the artists (unless they are in the Taylor Swift level) I have to say that young people these days are far more clued up to the history of music than I was at their age. My job brings me into contact with people in their late teens / early 20's, some of whom are hugely into their music. And seeing as they don't have to save up for an album (like us old buggers had to!) but can access anything they want to INSTANTLY then they've got the whole History Of Music at their disposal. This can be a good or bad thing. They might have the attention span of a gnat and dismiss classic songs because it didn't grab them in the first 30 seconds. But also they might be interested in the stuff from before 'their time' and see how it relates to the tunes that are fashionable these days and thus investigate acts that the likes of us are into.
Does NMA's music speak to 'young folks'? Absolutely if they're interested. Likewise, 'young persons music' might appeal to us oldies... the very fashionable Olivia Rodrigo headlined Glastonbury last year, I saw her set on the BBC and I thought she was excellent, pop / rock with great lyrics and she was a terrific performer, I consider myself a fan!

Age has nothing to do with it. Good music is good music and people will find it regardless of age, especially in these days when it's so easy to find.
