Substitution Cipher Puzzle

That memorable phrase, often used to describe a setback, defeat, or even death, gained immense global recognition as the title of a legendary rock anthem. While the idiom "bite the dust" has roots stretching back to ancient texts and gained prominence in the 18th century, it was the powerful bassline and iconic vocals of a certain band that cemented its place in popular culture. The expression vividly portrays a dramatic end or a moment of failure.

The song was a massive hit for the British rock band Queen, appearing on their 1980 album "The Game". Written by bassist John Deacon, the track's distinctive funky groove was reportedly inspired by the disco group Chic. It became one of Queen's best-selling singles, reaching number one on the US Billboard Hot 100, a success reportedly encouraged by Michael Jackson's suggestion to release it as a single.

The puzzle you've unravelled utilizes a substitution cipher, a fundamental and historically significant method in cryptography. This type of cipher works by consistently replacing each letter of the original message with a different letter or symbol. Its origins trace back to ancient civilizations, with perhaps the most famous early example being the Caesar cipher, named after Julius Caesar, who employed it for military communications around 50 BCE by shifting letters a fixed number of positions in the alphabet.
