Earlier today, Mac Miller announced on Twitter that he is collaborating with Pharrell on a project called Pink Slime. Mac then tweeted: “can yall please get #pinkslime trending so me and pharrell can drop this song?” Pretty soon, the hashtag was trending worldwide on Twitter, hoping that the first single “Onaroll” would drop tonight. Instead, Mac promised that the single will officially drop tomorrow at 3 PM. Don’t worry Mac fans, it’s coming.
