The song was written by Andrea Corr, Sharon Corr and Caroline Corr. Andrea has said the first time she sang it in front of her parents, she was embarrassed because of the line "make love to me through the night". She noted that she knew her mother would be thinking "where did she learn that?!"
The song has a subtle key change. It is written in F major, but towards the end, the fourth (a B flat) gets augmented (becoming a B), so the key changes to lydian mode. Rhythmically, a similar change happens in the drums, which play a slow 6/8th at first. In the end, a snare drum is played on the 2-eh and 5-eh, which makes a double-time feel.
The video for "Runaway" (1995) was shot in Dublin, featuring locations such as Phoenix Park. The video is shot mostly in black-and-white with flashes of colour in certain scenes.
The video follows the band as they sing and perform on several locations, including a forest and train station platform. The video begins with Andrea on a train, looking out the window and singing, and ends with her getting off the train and running towards the camera.
Dani Jacob's fourth Corrs videos is, similar to "Love to Love You", compiled of backstage and concert footage; this time from one single gig at the Manchester Evening News Arena on 1 February 1999. It also includes a few scenes of the band in the recording studio with Tin Tin Out working on the remixed version of the song.
