Watch The President "Head Bobbing" To Lose Yourself!!!

PRESIDENT OBAMA used a rap song to get pumped up before his speech at the DNC last week.  And it was "Lose Yourself" by EMINEM.  Which makes sense, you only get one shot to take down DONALD TRUMP at a national convention . . . this opportunity comes once in a lifetime, you better never let it go. 

This came to light in a new backstage video.  Obama is head-banging to the track just before going on.  (In the video, it comes about a minute in.  There's a Vine of that moment as well.  And here's the original track.)
