Thrash metal is tops. The most skilled musicians, and by far the most adrenaline inducing testosterone amplifying music one can experience. I like all forms of metal, but death is too easy to play (though not all) and is just too repetitive. There are so many death bands now that it's no longer innovative or unique as it was in the early 90's with Cannibal Corpse. Still, a few good stuff filters through all the garbage. Anthrax, Metallica, Megadeth, Evile, and especially Testament are all highly skilled musicians always with something new and fresh yet within the genre.
