Now if you're listening to Sevendust, even a balanced system (no need for artifical bass boosting) you should be able to hear the bass guitar well enough and still have enough kick in the bass drum. Boost that, and it's like being in the very front row of a concert, which acoustically speaking is never teh best place to be in (visually of course it's the best experience regardless of who's playing, just don't try to take photos of Axl Rose or he'll smash that camera or smartphone).
I don't listen to a lot of rock/metal, but there's a bit of deep house in my music. I've listened to the same songs on some mid centric IEMs and Headphones, and one with a slightly bass heavy signature.
I think different headphones bring out different aspects, I've never felt that the song needed more or less bass, maybe because the vocals and other stuff was shining through.
So I guess it boils down to the complexity of the music as well. If all the track consists of is thumping bass with some poorly recorded/performed vocals and nothing much in the mid range, then yes, it'll sound boring without bass.
But, for others, like jazz, a bit of a bump in the mid-bass and bass brings out the double bass very nicely, and mid centric EQ presents the vocals and accompanying instruments....
The perfect combination would be ofcourse a totally flat system.
