Please, please, please, please do NOT put System Of A Down in the same league as Limp Dickshit, Linkin Park, Korn and Static-X. It's just not right. OK, you may not like SOAD, but I'm sure you cansee that they are a completely different kind of animal than the bands they are grouped with. IMHO Toxicity is a brilliant album, and SOAD deserve all the praise they get.
But anyway, enough with the nu-metal debate, back to Soilwork. I agree that there is a slight hint of nu-metal(ish) influence in NBC, but there is NOTHING wrong with that IMHO. I think it gives them a fresher sound. At least they're not like fucking Manowar who keep making the SAME (shitty) album OVER AND OVER. At least Soilwork progress and change their sound. If you want to hear the same sound, just put on Steel Bath Suicide and put the album on repeat, and pretend you're listening to their new album.
