Busy today, but can you tell me how tomorrow sounds?
Mac has things going on today but he still wants to see his girl so he’s wondering if she’s free tomorrow.
This could also mean not literally tomorrow, but instead is a reference to how his life is at the moment. He does not have the time for a girlfriend because of how busy the rap game is, but after he settles down with rapping he can foresee a future with his love
Alternatively it could be a reflection of how people never have time for him anymore, constantly making excuses to want to reschedule/postpone.
