I actually generally prefer male musicians. My all time favorite musician ever is a male, and most of my other favorites are too : p
Its not that I dont like any female musician, I like several of them. I think its just the style of music they write, like I think female artists generally take a more like personal stance with their art, like most female musicians write songs about themselves, about relationships their in, about people they know, it always comes around to being about them. And for the most part (from my own observation) female musicians are generally more prone to writing over the top dramatic music, which is something that I dont personally enjoy. I prefer much more laid back and gentle music that works off your imagination and leads to like some self reflection.
It seems like this kind of music is mostly done by the male gender, they more often than not are the ones who write more flowing, mellow music with ambiguous lyrics that you can turn into anything you want to. Its because of that that I believe males make better musicians : p
