The Boss admitted back in October (16) he had penned a ballad for the first movie in J.K. Rowling's wizarding saga, but it was never used. However, on Friday (10Feb17) it appeared on music website SoundCloud, according to Billboard.com.

Fans were able to listen to his track I’ll Stand By You Always, which was was recorded in 2001, for a few hours before it was taken down from the site. The song doesn’t have any direct references to Harry Potter, although it includes lyrics like, “We'll let the night come and do what it may, together we'll find the courage, we'll find faith/ Until you awake.”

The 67-year-old rocker revealed in October (16) he offered up the tune, which he wrote as a tribute to his son, for the movie franchise, but for whatever reason studio bosses decided it wasn't a good fit.

"It was pretty good," he told the BBC. "It was a song that I wrote for my eldest son, a big ballad that was very uncharacteristic of something I'd sing myself. But it was something that I thought would have fit lovely."

And Springsteen is determined to work the ballad into another family film. "At some point I'd like to get it into a children's movie of some sort because it was a pretty lovely song," he added.

Springsteen's music has served as the soundtrack for many classic movie moments - his Streets of Philadelphia song set the haunting mood for Tom Hanks and Denzel Washington's 1993 film Philadelphia and his music has also featured in movies like Jerry Maguire, The Wrestler, Warm Bodies and Everybody Wants Some.

The first three Harry Potter movies were scored by composer John Williams, while the five subsequent films featured music by Patrick Doyle, Nicholas Hooper and Alexandre Desplat.
