You're rite that's a bad idea. I think I meant a "COB style song" in different metal genres. Well. Kinda boring, as there's nothing interesting for me to anticipate in the music world. All these great 90's metal bands lost some of their epicness so it's not the same thing anymore... I'm still waiting for a band that makes black truly properly, not just nice bits here and there. And I'm waiting for another good doom band besides Swallow the Sun. I could listen to the trance-like blastbeats of black metal with magically dark atmosphere forever, just as I could to the incredibly slow, dynamic and powerful world of doom. Almost every band in these genres sounds shit and just wrong. And another good melodic death metal band with aliens in the music, besides Hypocrisy...

This sounds like sailing on a stormy and treacherous dark sea.
It's hard to tell what you want out of music. I've recently listened to Time 1 again by Wintersun and in my opinion it doesn't really get more atmospheric than that. Check it out if you haven't.
