You should start hearing a difference in pre-recorded clips, too. YouTube is introducing spatial audio to on-demand clips, so you'll know exactly where that guitar is coming from. There's no mention of spatial sound for live feeds, unfortunately, but this and the as-it-happens support both help bring 360-degree video (and by extension, virtual reality) further into the mainstream. You no longer need to go out of your way to get some of the most immersive video experiences, even if you don't happen to have even a basic VR viewer on hand.
