IMO albums that are that way are usually the best. When I for instance first got "Bloody kisses" by Type O Negative I was like "Yeah, that's alright" and then threw it on the shelf. A little later I took it out again, started listening to it and found out that it was a superb record! When "October rust" came out I was dissapointed. It was alright, but not exactly what I had expected. I kept listening to it and now I think it's better than "Bloody kisses". When I got my hands on "World coming down" I was like "Yeah, that's alright", but also a little dissapointed. Now I think it's a superb album, but still has to beat "Bloody" & "Rust" though. Maybe it will in the future, as "Rust" did it to "Bloody".
When I first heard Dimmu Borgir's "Enthrone darkness triumphant" I was like "Goddamn! Superb record!", heard it a lot, but has now grown a little tired of it, although I still think it's a great record! I think that a lot of times when music gets you totally the first time it can get tiresome after a while, but maybe it also depends on what kind of music it is. Stuff with energy and shit can get tiresome after a while, but I think sad music often stays good. But then it might be another thing, as more or less all the sad stuff I know is from the 60's and all the stuff I know with energy and power is from the 70's or metal from the 90's and as I've commented on before I think, I feel that quality in music went downhill from the 70's and forwards.
