We Remain is being released as a digital download today, but it has already appeared on music-sharing website Soundcloud.
It is the second song from the movie's star-studded soundtrack to reach the public, with Coldplay's Atlas making its public debut last month.
Ellie Goulding, Sia and The Lumineers also feature on the soundtrack.
The album is getting a release on 18 November, shortly before the movie goes on general release on 22 November.
A new promo picture was revealed yesterday.
