“Quodlibet” is a combination of the Latin words “quod” and “libet,” directly translating to “that which is pleasing.” But the more modern usage of this Latin term is “song mashup.” Think of a cover band playing a medley of the choruses of crowd-pleasing tunes, or a classic Hollywood movie showcasing dancers twirling to a medley of well-known songs. The “Pitch Perfect” movie series brought the tradition into the 21st century with its acapella riff-offs (improvised quodlibets). In the first movie, the Barden Bellas lost to the Treblemakers as the groups sang a quodlibet including “Mickey” by Toni Basil, “Like a Virgin” by Madonna,” “No Diggity” by Blackstreet, and “S&M” by Rihanna.
