All or Nothing (O-Town song)

"All or Nothing" is a song by American boy band O-Town. The track was written by Wayne Hector and Steve Mac, and produced by Mac. It was released on March 20, 2001, as the second single from their debut album, O-Town (2001). The song reached number three in the United States, number five in Canada, and number four in the United Kingdom.

In 2006, Irish boy band Westlife recorded a cover version on their seventh studio album, The Love Album—to which was used extensively as background music during the audition stages of The X Factor UK. The song itself charted without being properly released as a single in the United Kingdom. Westlife later revealed that the song was first offered to them but Simon Cowell, their executive producer, rejected it and passed it on to O-Town, becoming their hit. Rolling Stone ranked the song as the 32nd best boy band song of all time.
