A single take says we practiced like crazy / we are fucking awesome. Nothing fancy here.
Singing/rapping over your music live makes you badass.
Plus it doesnt hurt to throw in a  few  "Hello sexy", "Fuck You!", and then show your ass.
The single take, drinking, dancing, driving, live rapping, and dual lyrics. It gives a feeling of this is real. Weird camera angles, quick flashes, or special effects, they just basic!
