I listen to more Heavy Metal music these days than when I was younger, when the music was newly released. For example, Black Sabbath's Heaven and Hell is in heavy rotation, especially with my RAAL CA-1a phone and the VM-1a tube headphone amp. My uber rock and roll setup. I never paid too much attention to it back in the day though it got a lot of radio play.
@yyzsantabarbara I remember driving around in a 86 Pontiac Sunbird (barely legal to drive once upon a time) with "Die Young" from that album turned all the way up as much as the crappy stereo in that car would let me. Imo, Dio's vocals just gelled better with Iommi and Ozzy was better off with his solo works.
I listen to many genres, but, my playtime with this genre has gotten more as the rigs/rooms got better.
