Tainted Love
From Tardis Wiki, the free Doctor Who reference
"Tainted Love" was a song played at Gwen and Rhys Williams's wedding reception in 2009 (TV: Something Borrowed)
In 5,000,000,000, the song was also played on an antique "iPod" (actually a jukebox) aboard Platform One shortly before the destruction of Earth. The Ninth Doctor danced to the song. (TV: The End of the World)
Behind the scenes
On both occasions, the song was the version performed by Soft Cell.
