While listening to the same song in different settings?
I will listen to a song while running, then the same song while drinking, or while very tired, and there is a frighteningly noticeable difference in the tempo.
I guess because my mind is slowed down while drinking or tired, so external sensations appear faster.
It's so coo
If I expect a song I've heard many times to be faster, then it seems slower when I actually listen to it, and vice-versa.
