Who's your favourite blacken folk metal band? What about your favourite kraut rock band?
One thing I've noticed is people who claim to have a very wide taste in music generally don't really have as much diversity in their listening habits as they think they do. There will be huge areas of music that you know very little about. There's nothing wrong with that, but trying to claim you listen to a huge range of diverse music is a dubious position to take. There is so much music out there one can't possibly hope to be intimate with even the big players in every single genre.
Take "heavy metal" for example. If you think that listening to Metallica, Iron Maiden, Black Sabbath et al means you have a diverse taste in metal then I'm afraid you are sorely mistaken.
I spend a lot of time listening to metal music but I can't name all of the subgenres that exist. I can't really profess to be an expert in the subgenres I listen to a lot except perhaps when confined to a specific geographic region.
Sorry to jump down your throat like that, but people claiming to have a diverse music taste is one of my pet peeves. I listen to a lot of music but I know I don't listen to everything - far from it, in fact!
