Lil' Wayne used Waka Flocka Flame’s “O Let’s Do It” beat on the No Ceilings mixtape, notably, many months before Flocka and the track had really gained popularity and everyone started doing freestyles over this beat.
Wayne goes hard on this beat — no hooks, no frills; gotta love it
The first verse riffs on the original lyrics for example;
“I fucked my money up / Now I can’t re-up"
“I got Young Money up / And now I got my feet up”
and so on
