I'm not totally sure what this thread is about, haven't followed closely. However....
Something happened and/or occured yesterday. A weirdness. It's not the first I've noticed it. The radio was static, not quite picking up the station. I could tell what song was playing, but the key was unclear, and seemed to constantly keep changing. Even the melody seemed a stylized version, different from the original which was actually being played at the time. It reminded me that it's something I have noticed in the past, such as approaching a bar/club and hearing through the walls the band playing. I can tell what song is being played, but the key is unclear or off, changing, and the vocal is not singing the correct melody, some weird stylized version that in a weird way almost works. Odd. I don't know what that is, maybe it's just me. Maybe it is the brain attempting to understand what is being heard, working it out in real time.
