And the all time best metal band is.... Megadeth, hands down. If you span their career, there are no weird "we gotta do something different" albums except Risk. Yet, Dave always rocks hard enough, and throws in enough twists, to keep every album fresh and great. Don't take me wrong. I love Metallica. They come in 2nd overall, but also second on this list. I've also seen Megadeth 3 times, over a fairly broad time period (probably around 15 years form first to last time I saw them) and they are freaking TIGHT and GREAT in concert. And, despite what I'd heard, Dave was cool as heck when we met him.
