A new Reddit thread has popped up that provides players with a link to a previously unreleased album of music from Destiny 1. The album, Music of the Spheres, was composed by Paul McCartney of Beatles fame, Martin O'Donnell and Michael Salvatori. According to Kotaku, the album was never released by Bungie after O'Donnell was fired. The caveat in this is that the album has been released by a user named OS_Epsilon who has shared it and it is not an official Bungie release.
You can head to this Reddit thread to check it out for yourself and to download the album that contains music designed to thematically represent nine of the planets and The Traveller from Destiny 1. You can also listen to it in the video below.
Whether or not Bungie will allow the continuance of the provided links remains to be seen.
