The barber shop is not spatial audio. It's a static stereo mix, and a terrible example of how the medium actually functions. I know what good spatial audio sounds like, too: I've used 6DOF with headphones and fancy Atmos filters, and it works great in VR. Everywhere else though, it's just distracting.

We have lost the stems to probably 95% of all music ever made. If all of our old music sounds bad in spatial audio, how will it ever hope to become the new standard?
