No. I find it ridiculous that bands, as they're working on their new material, invariably release a statement that says, "Our next album is going to be heavier and darker than..."
How much heavier and darker can music become? None, as Nigel might say.
By today's standards, the first few Black Sabbath albums wouldn't be considered heavy. They're not particularly loud. They're not fast. They aren't a wall of sound. But no one has ever created heavier riffs, in my opinion.
So heavy is relative.
I prefer melody to heavy, anyway. As Jon Drenning told me, create a melody that sticks in my head. That's a great song.
In my 5-CD changer, on any given day, one could hear albums such as these:
(500) Days of Summer soundtrack
Amorphis - Skyforger
Glenn Miller's Greatest Hits
Astra - The Weirding
Dave Brubeck - Time Out
I like to mix it up.
