Season 20 of America's Got Talent is so golden! Ever since the NBC show kicked off a new season on May 27, viewers have been entertained by a wide variety of acts hoping to win the $1 million cash prize. While judges Howie Mandel, Mel B, Sofía Vergara and Simon Cowell have sat through some questionable performances worthy of the giant red X, they've also had a front-row seat to must-see talent. This season, the judges - alongside host Terry Crews - had the opportunity to pick two acts worthy of the Golden Buzzer.
