it's true but look at this.5.1 surround mixes like "Dark Side of the Moon" and "Wish You Were Here" will probably never be 'redone' simply because that's how the artist agreed it should be.
James Guthrie and Andy Jackson have absolutely different approach to surround mixes for same band/artists
and seems there weren't any complaints/refusal to print out either of two. for me it seems that in this case
musicians doesn't care at all.
most likely all depends on how close mixing guy stands to the band, to be hired for the job.
