In the late 1990s and early 2000s, melodic death metal quickly expanded with many bands emerging, including Amon Amarth, The Black Dahlia Murder, Arch Enemy, Soilwork, and Children of Bodom.[13] Additionally, other genres would begin using melodic death metal as an influence, including melodic metalcore[2] and melodic black/death.[3][16] Stewart Mason claims that melodic metalcore has become very popular in the United States, using the term "Swedecore" to describe Scandinavian-style metal as played by non-Nordic bands.[17] Many melodic death metal and metalcore bands (especially after melodic metalcore band Killswitch Engage rose in popularity) were heavily influenced by Slaughter of the Soul by At the Gates and had an influence of them in their music.[13] Many heavy metal bands in the mid-2000s, in turn, were labeled "At the Gates worship".[18]
