I've never thought about this before, but how many spins does a CD do in it's life??
Ziltoid is about 54 minutes long and if a CD is spun at about 500RPM (that's a guess assuming that 1X CD speed is 500RPM) you would have spun the CD 54x500 times, which is 27,000 spins per listen! To decrease that to allow for variability in the speed, 20,000RPM per listen.
If this is the 100th listen so far this year you could be on the 2 millionth spin with Ziltoid!
