Lifelover was a Swedish metal band, formed in 2005 by Jonas Bergqvist and Kim Carlsson. The band split up in September 2011 after the death of Bergqvist, as he was the lead composer and one of Lifelover's founding members. While widely considered being metal, Lifelover combined several genres into their sound, citing black metal, post-punk, dark ambient, doom metal and gothic rock among other influences. The band called their music "narcotic metal", which was described in a Decibel interview with Carlsson where he stated "anyone should be able to figure that out [what that means] or make their own conclusion about it."

With Lifelover's depressive lyrics, musicianship and atmosphere, the band are credited for being one of the biggest influences on the black metal subgenre depressive suicidal black metal (also known as DSBM).
