Disturbed are good, especially their early stuff. I'm like that with most bands... I have been trying to enjoy Black Holes and Revelations by Muse but its not a patch on their older stuff, and I end up skipping right to Kinghts of Cydonia most times.
I used to be (still am) into HEAVY stuff, like Obituary, At the Gates, Emperor, Vader... and for those of you into a brand of music called 'Necro', Anaal Nathrakh
