Pitch Perfect, a musical comedy by Universal Pictures released in September 2012, follows the Barden Bellas, an all-girl a cappella group, as the team competes against a fellow group from Barden University to win the Nationals competition.

Along the way, the group gets help from an unlikely source — Beca Mitchell, played by Anna Kendrick, an aspiring DJ with a penchant for creating mash-ups of popular songs who decides to join the club.

Mitchell's audition for the Bellas is a rendition of the song "When I'm Gone," performed to the rhythm of the Cup Game. It not only gains Mitchell admission into the club; it also became the film's rallying cry, spawning a number of YouTube covers and how-tos.

Then, radio noticed. Today, the song has been transformed into a bona fide single, having added an extra 50 seconds to its original length, coming in at just over two minutes.

On last week's Billboard Hot 100 chart, "Cups" reaches its highest peak yet, jumping one spot to No. 8 after finding a home on both pop and adult contemporary radio.
