Carrying two cans of paint, security looks at me awkward
I say third floor I'm late, paintin' Jimmy Iovine's office

from Macklemore and Ryan Lewis (Ft. Ab-Soul & Macklemore) – Jimmy Iovine Lyrics on Rap Genius

Meaning

He is dressed like a janitor and is carrying two cans of paint as his cover. While security does give him an awkward look, Macklemore just says he’s late for painting Jimmy Iovine, the President of Interscope’s, office.

Again, a possible reference to The Usual Suspects

The cans of paint represent art, thus serving as a metaphor for his music. He is getting ready to paint Jimmy Iovine’s office with his music and earn a record deal.
