I use metal. It is pretty irritating how confused people get by this, however. Whenever I say metal, they say "Oh, like Metallica?", I reply with "Well, they only the first 4 albums", they retort "What's wrong with their 5th album, Death Magnetic?" /facepalm
Other responses I get from ignoramuses for which they should be slain:
"Metal? You mean like Avenged Sevenfold? Oh, you say death metal? You mean Slipknot?"
"Metal? Yeah, I like KoRn, Tool, and Godsmack too."
The worst is when someone appears to be interested in the music I like and I play them a song and they reply with:
a) "I don't like it, I can't understand the words"
b) "They sound kinda like Disturbed"
