Going to pitch in:
Grew up in the 80's
Iron Maiden, Judas Priest, W.A.S.P., Saxon, Metallica (till Black Album, everything afterwards was pretty much Crap), AC/DC etc.
Not so much into Trash/Death/Speed, albeit i've seen Slayer 4 times.
Funny enough: on the side i like Rock/Metal-Coverversions of popular Pop-Songs and those Big hits from mainstream Radio.
It's just hilarious to watch peoples faces, when they first start complaining ("Oh, no! Not your Metal-Shit again"), and then start to sing the song along.. ("Huh? Whatzzat? Why do i know that crap?"). Just search for Halestorm - "Bad Romance" (Lady Gaga)
But i also like the exact opposite: I have a Reggae-Version as well as a Techno/Trance-Version of Linkin Park's "In the End".
Same with "Fear of the Dark " (Iron Maiden-Classic) as Techno-Version.
In short: I don't like a genre per se (Heavy Metal just because it's Metal), but i like songs.
Well, the exception to that is Hip Hop and all that crappy so-called "R&B / Soul" from the 90's & 00's. That is the only kind of "Music" you can chase me away with....
Highlights in my life:
Seen Iron Maiden 12 times, and been once on stage with them during "Heaven can wait" for the singalong part.
Right now i'm way beyond over 300 concerts in my life (I've seen Metallica as support Band for AC/DC in 1991),
those include Rolling Stones, Pink Floyd, Guns'N Roses, Black Sabbath with Dio, Deep Purple, Motörhead, Manowar, and a lot of others i don't remember anymore, since i don't collect concert-tickets.
