I guess that the HD mixes will be new and not ported over from one of the umpteen other mixes.

How many times can you remix Rumours? You reach a point where the person doing the mixing is essentially replicating previous mixes. I guess the Dolby Atmos can sound great if your theater is set up for it, but why not release the Blu-ray in 4k so that you can get a lot more data storage on the disc and pull an ultra-high-def mix out?

Notice, too, that “Silver Springs” is added to the track list at the end. That is probably the new track list for now and the future. Every subsequent Rumours release will contain that song in the running order. It’s a little bit ahistorical and changes the listening experience — the dying out of “Gold Dust Woman” is the way the album was planned. That silence as the needle reached the inner groove was weird and very Seventies.
