Redundancy and entropy are key in music videos.
Redundancy - "...is that which is predictable or conventional in a message...Redundancy is the result of high predictability..."
Taylor Swift videos have high redundancy because she always sings about romance and heartbreak, and her videos include footage of just that, including this one for You Belong With Me.
The video for Ok Go's Here It Goes Again is like the polar opposite to Taylor Swift videos, the song itself has nothing to do with running or treadmills, yet it is the centerpiece of the video. However it is fair to argue that as the video goes on, the use of treadmills becomes more predictable and the video becomes increasingly redundant.
Entropy is "...unpredictability"
A text is entropic if it contains unpredictable elements.
