Disturbed isn't a one hit wonder, that's for sure. Even if they had a hit track 20 years later after their first hit, that automatically takes them off the one hit wonder list.
Most one hit wonders come from the hip-hop scene. Some artists that I remember having one hit wonders...
Eiffel 65, AFI, Alien Ant Farm, Baha Men, Danity Kane, Amy Winehouse, Big Tymerz, Cascada, Crazy Town, Dirty Vegas, James Blunt, P.O.D
Probably missing a shitload.
