Interesting. I don't have a BR player, so I can't rip it (or even confirm)
I might try that (don't have the album, but I do have that 5.0 mix that was floating around months before release). If the only thing they did with that mix was just moving front left to rear left and front right to rear right occasionally then it should sound pretty much like the original stereo when mixed down.
Not a fan of the binaural?and still sound better than the binaural ones.
