Papoose's surprise performance at Summer Jam XX was one of the biggest head scratchers of the entire night, leaving a lot of people in the crowd, and on Twitter, wondering, who, what, when, where and why? Today, Pap claps back at the haters with a freestyle over Jay'Z's, "Open Letter," somewhat discussing how he hi-jacked the stage and part of the headliner's time slot. "They don't want to let a nigga shine. Fine I'll take another artists time," he raps. Hey, sometimes you got to do what you got to do.
