This boomer's gold standard is live, acoustic music - classical mainly, including orchestral, vocal and instrumental + some acoustic pop and jazz. I was a choral singer for many years, former church organist, played briefly in a band, and I'm married to an orchestral bassoonist. We've both got a pretty good idea what acoustic instruments and voices sound like in real space.
We play some rock too - but that's not our gold standard.
