Performed by the Glee Cast, "Bad Romance" is a high-energy reimagining of Lady Gaga's iconic pop anthem, originally released in 2009. The track features the ensemble's signature theatrical style, blending Gaga's distinctive vocal delivery with a driving electronic beat that defines the show's musical identity. This recording appears on the complete Season One soundtrack, which served as a critical launchpad for the series by integrating diverse pop and rock covers into its narrative. The song's inclusion highlighted the cast's ability to deliver complex, character-driven performances while maintaining the upbeat, dramatic flair central to the program's appeal during its early years.
