Debuted at #1 on the UK Singles Chart and stayed in the top 40 for 12 weeks. Themes and Composition

Focus on the intimacy of a private relationship—a "world of our own" where partners share secrets and find refuge from the outside world.

"World of Our Own" is a signature pop anthem by the Irish boy band Westlife, released in February 2002 as the second single from their third studio album of the same name. Written by Wayne Hector and Steve Mac, the song became the group's tenth UK number-one single, solidifying their dominance in the early 2000s pop scene. Key Facts & Production February 18, 2002.
