"Rotation" is the working title of a track from 1999's The Fragile. Stated in an interview with the Nailed Podcast, Charlie Clouser believes that it is an early iteration of "The Big Come Down", but could not say for certain. Rob Sheridan confirmed that it is simply an early version of a released song. [1] By process of elimination, it is likely to be either "Just Like You Imagined", "The Big Come Down", or "The Way Out Is Through".[2]
It is one of two tracks that feature in background photos from this era that remain unidentified, the other being "Stained", which may be a working title for "Underneath It All".
