Steve Sailer makes a great observation about one of the things it takes to achieve success in music:

To become a superstar, you have to embody some of the inner fixations of either the male or female publics. And in popular music in recent decades, the biggest names have had largely feminine audiences because male tastes have fragmented into multitudinous narrow genres, such as, say, Melodic Death Metal.

This is also important well below the superstar level; it's true that quite a few guys really like a specific subgenre of music but virulently despise everything else, including some closely related subgenres. Women tend to be less extremist in their stylistic preferences. It can be pretty difficult for a band working in a genre with a mostly-male audience to build a following.

Economically speaking, there is really not much sense in playing very guy-oriented music. As I've already alluded, if your band attracts women to its gigs then plenty of guys will show up to hit on them anyway, even guys who don't think all that much of your band.
