With the success of his mixtape K.I.D.S., Mac Miller enjoyed a nice 2010. The Rostrum Records artist is currently headlining his own 25-city "Incredibly Dope Tour," which kicked off back in January. He's got a new mixtape titled Best Day Ever on the way, and he managed to get #BestDayEver to become trending topic last night on Twitter. Afterward, he leaked this song from the upcoming mixtape. Now that's how you know he's buzzing on these e-streets.
