Why? (I know it depends also of the music style, but...)
Well yeah, it depends on genre, but for most electronic music, I prefer names that a bit more playful. Artists that use their own name tend to (NOT ALL THE TIME I KNOW IM NOT TRYING TO OVERGENERALIZE) take themselves too seriously. With folk like that, good music or not, i tend to tune out a bit. I'm a fickle fuck who loves hunting whales and my opinion doesn't matter at all. Don't listen to me.
my music name kinda sux but i reckon im stuck with it now
