Whenever I hit the gym really hard, I notice that when I get back in the car afterwards and put the cd player back on, the tune I listen to seems to be in slight slow motion. Not ridiculously so, but definitely noticeably so. Invariably, it will be the latter half of the former half of the tune I was listening to as I pulled up, so it's still fairly fresh in my head as I get back in the car. Am I going nuts, or does anybody else get this?
