Mac Miller is known as one of the hardest working rappers in the game, and though his GO:OD AM album came out just a few months ago, it appears that he's already getting back into the studio. In fact, it looks like Mac is about to dive into a Metro Boomin beat pack and create some magic. No word on if Mac has these Metro beats set aside for a new project, but based on the two's conversation on Twitter last night, fans are probably in for a treat whenever Mac decides to drop what they cook up. Stay tuned.
