Just weeks ago, Queen drummer Roger Taylor confessed he could only hope that the track, There Must Be More To Life Than This, would feature on the new release after revealing that dealing with the Jackson family and the King of Pop's estate officials was like "wading through glue".
But it seems all parties have come to an agreement, because the unreleased song, recorded in the early 1980s, will appear on Queen Forever, which is scheduled for release in November (14).
The track, remastered by super-producer William Orbit, is not completely new to Mercury fans as he featured a solo version on his 1985 album Mr. Bad Guy.
Queen's two-disc new album will also include the completed version of Let Me in Your Heart Again, which was cut from the group's 1984 album The Works, and a new version of Mercury's solo hit Love Kills.
Guitarist Brian May calls the new collection "things that we have collected together that are representative of our growth rather than the big hits".
Meanwhile, Taylor calls the compilation "a definitive collection of Queen's timeless love songs".
