apparently the composer Erik Satie (famous for his Gymnopedies) wrote a piece of music called Vexations that has, at the beginning, instructions on how best to prepare oneself to play the piece 840 times in a row. Nowhere is there any actual indication that anyone would ever want to do this, but the instructions are there just in case anyone does.
@Felthry To be fair it was written in a time before radio existed and before recorded media became publicly accessible, so if you were a piano player working in a bar or wherever there was a *very* real chance you'd end up playing the same piece a bunch of times in a given night.
