I've noticed something throughout the years that I've always been curious about when listening to the radio. Do the DJ's actually have a way of being able to speed up the song.....playing a slightly faster version of the original? Because I will always notice when a popular song comes on and its just going a bit faster than usual! I know its not in my head! Do DJ's do this to make sure everything fits into the allotted time they have to run their show?
