> I grew up playing a lot of jazz in the late 2000s and there was always a strict canon - big band was seen as kind of cutesy and not worth putting much effort into

Rock used to be this way too. It’s hard to believe now, but there was a real wall between punk and metal in the mid 1980s.

In punk circles grudging respect was given to Motörhead and a few thrash acts but everyone else was seen as hair-obsessed posers or dinosaurs. Neither camp would admit to liking anything “mainstream.”

20 years later Chris Cornell is covering Billie Jean (https://youtu.be/R0uWF-37DAM?si=V3Pqtq-3GDHqxJBd) and all kinds of unusual collaborations were kicking off. It was frankly refreshing.

I think that is what the lyrics here are referring to.
