It is common knowledge that Barack Obama is a fan of hip-hop. The President-elect often lists Jay-Z, Common, Kanye West, and Ludacris among his favorite musical acts. And when Obama is sworn in as the country’s first African American president on January 20, 2009, he may bring this musical love to the party. Several sources report that Obama is in talks with Jay-Z to appear at the inauguration ceremony. Awesome.
