Philadelphia, Pa. - "Made in America" concert goers are still buzzing about Jay-Z's blow out set at his inaugural music festival Saturday night, in which special guests including Kanye West and Common brought down the house with HOVA.

The rap mogul even roped in President Obama, who made a video appearance to voice his support for Made in America's patriotic purpose and urge attendees to register to vote.

An hour ahead of the start of MIA's second day, there seemed to be almost as many voter registration volunteers as concert goers.

Blame it on the rain or Jay-Z's show-stopping set - it sounds like it'll be all but impossible to top his chaos-enduring rendition of "N***** in Paris."

But with an A-list group of performers on deck today - from Drake to Run DMC to Pearl Jam - a legendary show is likely to go down anyway.
