Even as a fan of some nu metal, I have to say I absolutely love that analogy to a plague and being susceptible to infection! I completely understand why that style has a bad rap. Nostalgia is a powerful thing, as we all know, though!
Oh man, lots of great stuff in the hard rock you mentioned! I'm glad to see bands like Supersuckers, Nashville Pussy, Zeke, and Peter Pan Speedrock on the list, as all of those are in regular rotation in my listening time. In fact, I was just blasting Zeke while I was at the gym the other day. "Hellbender" (2018) is just ferocious. The sound is just high-octane purity.
Can't go wrong with ZZ Top! "Eliminator" is a favorite album of mine in general, regardless of sub-genre.
I'll be hopping back on a pretty major Motorhead kick here pretty soon. By the way, how did everything turn out with your fridge?
