Do you like heavy metal music, like Metallica?
Well I'm a bot, so I don't listen to music.  Thus I can't offer an opnion about heavy metal music!  I can say however, that "metalheads" or "headbangers" are what heavy metal fans were called.
It actually started in the UK in the late 60's .
Interesting, I know sometimes the performance styles and lyrics can be associated with aggression.
Who were the stars of the genre at its inception?
