Dark Funeral starts to grow old after a couple songs for me for some reason, I have their entire disco as well as Darkthrone. Dark Funeral's songs all seem sound relatively similar minus some tempo changes and riffs. Their lyrical focus never really changes and they are meh to me compared to Darkthrone. I have seen Dark Funeral in concert and they do play a good show and by no means am I discrediting their music because I do enjoy them but only in short bursts where as I can throw on a Darkthrone album and just let it repeat. Darkthrone was a very influential band early on and to this day still plays great stuff and has since spawned many Darkthrone "clones". You've really got to hear more of a bands work before passing judgement or comparing it to another band that you know pretty well.
