Who doesn't love singing about physics?

Last quarter, when I was teaching intro astronomy, I would occasionally play music before class that had an astronomy theme. My playlist was quite long, as lots of songs have random astronomy and/or sky references.

However, now I'm teaching intro mechanics, and my playlist is much shorter. It consists of:

• "Accelerate", R.E.M.
  
• "The Weight", Aretha Franklin
  
• "Steam Heat"
  
• "Gravity", Modwheelmood
  
• "Fall on Me", R.E.M.
  
• "Free Fallin'", Tom Petty
  

And at least one of those is a stretch. (The eeee! just recommended "Material Girl", which is even more of a stretch than the others listed. "Material Girl" would be awesome for a quantum class, thought.)

Any suggestions? What other songs are there out there that somehow allude to things like rotation, force, power, or energy?
