Arizona DJ Guy Zapoleon played UB40's "Red Red Wine" four years after it was released as part of a feature on songs that should have been hits. Listeners started requesting the tune and within weeks it was topping the Hot 100.
Kacey Musgraves originally offered "Follow Your Arrow" to her friend Katy Perry. However, Perry thought Musgraves should record the song herself as it seemed, "like something that you would totally say."
The lyrics for "Mary, Did You Know?" were written by Christian singer and comedian Mark Lowry, after his pastor asked him to write a Christmas musical for their church. Southern gospel musician Buddy Greene later added music to his words.
