Jay Z 4:44 Concert, Philadelphia Freedom For Meek Mill

Jay-Z was on Meek Mill's home turf Friday night and showed rousing support for the "Free Meek" movement.

Hova played the Wells Fargo Center in Philadelphia as part of his 4:44 tour, and played Meek's song, "Dreams and Nightmares."

Jay ended up leading the crowd as everyone joined in.
