Coming in at No. 41 is the internet's favorite black metal band, Immortal. From the band's 2002 full-length, 'Sons of Northern Darkness,' the opening track, 'One By One' is an absolute beast.

As one of the most purely heavy black metal tracks of the 2000s, 'One By One' sticks to black metal principles while luring in thrash and death metal fans with slight characteristics of the genres.
