mac miller incase ya didnt know is an upper middle class suburban white rapper kid from pensylvania who's besties with whiz kalipha. his jam donald trump  got 53 million views on youtube and was acknowledged by the donald himself who declared him the new eminem and said " who wouldnt be flattered?"

while having the blessing of the king of atlantic city casino real estate and highly questionable combovers is hardly the brass ring most up and coming rappers look for it's totally working for mac miller who had a number 1 album and is back with this.. which is just ridiculously impossible to get out of your head after the 1st listen

plus the video is old school retro entertaining in a 50s taking your best girl who will definitely put out because she's catholic to the sock hop after getting a  malted daddy-o way... which is so much more awesome than annoying ska bands doing their best to recreate 90s dockers commercial

 it's mac miller it's knock knock.. enjoy
