Amorphis started losing me with "Elegy" and I only purchased "Tuonela" after that. "Tales..." is still my definite favourite, and from what I have heard of the new album through their MySpace, I'm not entirely sure whether that's going to change any time soon. (That would be "House of Sleep"... "Leaves Scar" wouldn't load.) I'll give the album a listen at the record store, though.
I don't know why, but generally speaking Amorphis just don't "do it" for me anymore. And I'm not just saying that to sound cool and/or old school - I couldn't care less.
