While that's heavier than I tend to like, I don't get people who feel that way. I have a good friend who can't stand any amplified music at all. (Or so she says... I always have to wonder just what she's heard to base that opinion on, but that's another story altogether.) Your guy's complaint strikes me as very odd, though. Almost makes me wonder if there's some sensory issue in play here because I can't imagine not being able to follow both the driving beat and the melodic line. That song, for example, has a great deal of contrast. Very odd.
