You want to meet Big Sean? Well, here’s your chance to. The G.O.O.D. Music rapper, who released his highly anticipated sophomore album Hall of Fame today, will be at Best Buy in Union Square to sign autographs for the first 500 fans that purchase his album (standard or deluxe.) In addition to this, upon purchase of the CD at this location, fans will be offered another opportunity for this day only to buy a pair of Sol Republic Headphones which will supposedly be 20% off—that is. Do remember it will be a first come, first serve when it comes to the autographs, so arrive early.
