Jay-Z's "U Don't Know" has always got me amped the hell up. I mean seriously, if this song doesn't get you motivated...
The entire song is filled with powerful lyrics that speak of rising above your circumstances to make it big, real big.
And as much as the track's intro where Jay storms in and spits "I'm from the streets where...", I feel the Best Part of the Song is from 2:32 - 2:38 below when Jay spits:
"Was born to dictate, never follow orders/Dickface, get your shit straight, fucka this is Big Jay"
There is something so defiant about the way Jay spits the lyrics. It's like something everyone wants to say to their boss when they are given orders but can't. Even the way Jay says "fucka"...it's like he's spitting on those who doubt him. Incredible.
