If there is one thing a Human should do, then, I believe it should be to have a hobby, and then find someone to pay you for it.
My preferred genre to DJ is House & Bass - I just love the warps and basses. And I love the crowds reactions when I play the genre of music. House & bass is a good genre to play as it features the Happiness of an House track but also features heavy basses.
I also DJ Electro House, Deep House, Tech House, Chart, Dance, Club.
