This is the point, though. About half, or slightly under, of the sales in the US are of a relatively small group of artists at any one time. But the rest? They seem to be smallish runs of LPs that are, as you want, music across genres.
To see this, let's pick a small selection of 2023 releases and rereleases that haven't made those 20 classic rock big hits:
- Albert King, Born under a Bad Sign
- Joshua Redman, Where Are We (Blue Note, jazz)
- Elvis Presley, From Elvis in Memphis
- The Preachers, Stay Out of My World (1960s garage, mono)
- Víkingur Ólafsson (piano) Bach: Goldberg variations
- Hilary Hahn (violin) Ysaye: Six Sonatas for Violin Solo
- Wiener Philharmoniker, Claudio Abbado: Tchaikovsky: Symphony No 4
- Lee "Scratch" Perry: King Perry
- Bert Jansch: Toy Balloon
Five minute's work to find classical, jazz, folk, pop, music from different decades
@MattHooper has listed a few prog albums in this thread already, there will be other releases dotted through.
Ten minutes' work to find these. The various hifi magazines all have reviews of audiophile vinyl of various degrees of obscurity: I haven't chased up MFSL or Analogue Productions in that list either.
I suspect a trip to a couple of record shops would throw up a lot more. So no, it doesn't crash, and these small quantity releases are selling to collectors, and those continuing users of vinyl, as much or more than to audiophiles.
Those small quantity pressings have continued since the "demise" of vinyl in the early 1990s that gets referred to. When I talk about suppressed demand for LPs, I'm on about these releases, not the few big sellers. The difference is now that the numbers of such releases have also multiplied, and they include new and older releases from major labels (I have a couple of DG in there, new and rerelease on that label).
if it was "en masse" we'd be talking 30 times or more overall sales. So, while not that, it;s not what you are seeing, either.
