Oh yes, Necrophagist isn't very odd at all in the grand scheme of things. Not much of a fan myself but I do like comparable bands like Origin or Nile. Much odder is noise like Kylie Minoise, Filthy Turd or Lambsbread. It's really not a big deal though. Many good friends of mine don't understand why I like a lot of the music I do but I don't see why this should make me feel guilty about it or try to hide it. Who cares? It's just a bit of music.
Yes, my answer has always been "because I enjoy listening to it".
well, thats what i use, but still, its hardly something i advertise, because quite simply almost no one will get why or just think worse of me for it. so no big deal i can listen to what i want, but i still find it awkward explaining to girls why i would enjoy listening to a song called "fermented offal discharge" (but really, the solo is sweet!).
and yes nile kicks ass, i just got their three latest albums, havent tried Origen, are they good? yeah, ive listened to metal for a long time, but i still want into this sort of thing until very recently, so i understand why other people wouldn't want to hear it.
