It’s cool. I hope it catches on in a way - more than the rare 5.1 mixes of albums did - because music has basically been recorded in stereo for so long (following mono, obviously) largely because hi-fi and headphones have been… stereo. Two ears and all that.
Hi-fi stereo listeners these days are probably in the minority as far as who is listening to music at a given moment these days, so if the ability to realistically create a 3D soundstage in your head becomes more normalised due to improvements in audio hardware/software in phones/buds/in-ears, maybe it’s time more musicians embraced the chance to explore than instead of the normal pan left - centre - pan right, with the different tracks in the mix.
