There's only 2 male vocalists (Chris Brown & Jonas Brothers) in my overall top 20 artists on last.fm. And there's only 1 song by male vocalists (Jonas Brothers) in my overall top 20 tracks on last.fm.
I listen to more female songs, but I prefer male vocals.
Male vocals, if the range is really high, is a big impressive one.
Female vocals are in high pitch, and any mediocre song will be a piece of cake.
Male vocals are much more of an impression.
Wait, am I making any sense? I'm confused as I type this.
