The time, place and company matters --
I love classical, opera or maybe baroque, on a quiet Sunday morning while reading the paper and sipping coffee/tea perhaps by the fireplace.
But if I'm in a dance club techno or house music is fun, though I would almost never listen to it outside of that atmosphere.
I listen (with headphones) to speed metal and death metal when inputting at my computer at work. It works well to put me in the sort of trance state of mind that I need to block everything else out and just let my fingers fly.
I can even appreciate my son Rap and HipHop at times..new Eminem is out and I find him fun, very cleaver and talented with lyrics/rhyming.
I really love Blues (and some types of Jazz) which is really where Rock---->Hard Rock---> Metal came from.
Anything that's got electric guitar gets a listen, I just drool over awesome guitar. And I love keyboards too......I think I've gone on long enough.
Recently I've been listening to Jet, love their whole CD Get Born. I think it may end up on my all time favorite CD list. Right now I'm listening to Bowling for Soup (yeah, I know sounds like every other pop punk band) but I like it and I get a kick out of the song 1984!
