"Shepard's Pi" is one continuous song that lasts for 999,999,999 hours, or about 114 years.

Canton Becker

Canton Becker composed these sounds and an algorithm that orchestrates these sounds using the first one billion digits of pi (π). Each digit (3.1415...) determines four seconds of music, supplying the "turn signals" used to determine every musical expression.

Because the numbers in pi never repeat, each of the million hours of "Shepard's Pi" music are in fact unique. By fast forwarding to some distant moment in the song, you are virtually guaranteed to find yourself listening to something that nobody else – including the composer – has ever heard before.
