I absolutely detest Disturbed. They're horribly overrated and their music is among the worst the nu-metal genre has to offer.
Despite the band's efforts in the last few years to appear more "mature" by adding in some half-assed guitar solos in their songs, their music is still watered-down MTV garbage that can be perfectly summed up as "metal music for people that don't like metal music." Idiotic wigger singing, bland rhythm section, and cliche downtuned guitar chords with some dumb "beeping" sounds once in a while. That's what Disturbed is made of.
Along with Kanye West, Disturbed is among the worst things to come from Chicago in terms of music.
You don't have to listen to Tampa death metal or Norwegian black metal in order to be a respectable metalhead, but at least stick with actual quality metal music if you want to get your metal fix, such as Iron Maiden, Slayer, Black Sabbath, Megadeth and so fourth.
