The friction between movie fans and music fans when it comes to the Blade Runner soundtrack never ceases to amaze me. I see that 11 other bootlegs have already been added to the Blade Runner release group, so why not one more?
A case can be made, though, that all the bootlegs should be in a separate release group.
As far as I know, they are all extracted from the movie soundtrack, so they are all related to that “recording”. However, the Vangelis album itself is a significant rework of the material used in the movie, with extensions and variations (and omissions!), in order to make it a music album rather than a compilation of sound cues. This is the root cause of the friction, and the reason why the bootlegs have been created in opposition to the Vangelis album.
The bootlegs are not of the album, but of the movie. And the bootleggers themselves emphasize how much the album is not a proper soundtrack of the movie.
For that reason, I consider the album, its reissues, its unauthorized copies (if they exist) to be a separate release group from the movie sound track bootlegs.
