Responding to myself here. Out of curiosity, I just did some AB'ing
(hadn't in a very long time) and you can hear a difference even above
192 kbps. A lot of it seems to have to do with emphasised frequencies. I
think Jostein had a very good point about these formats potentially
actually being pleasing to people because they make things sound
"bigger/punchier".

Very interesting...
