Or should I sell my music .zip to buy your zip
And hope one day it flourish to a kilo, track record of a hustler

from Kendrick Lamar (Ft. BJ The Chicago Kid) – R.O.T.C (Interlude) Lyrics on Rap Genius

Meaning

He’s asking if he should try to sell his music online (i.e. through .zip files) to get enough money to buy an ounce of weed, and then sell to buy a kilo, which would be a “track record of a hustler” (a play on kilo as in kilometer, and track as in track & field).
