Mozart took the classical era by storm and left his mark in music that still resonates strongly today since his debut at the height of the Age of Enlightenment.
His most famous compositions include 'First movements of Symphonies 25 & 40', 'Ein kline Nacht Music', 'Requirem', and 'Piano Sonata movement "Alla Turca"'.
One little-known composition, which was only discovered in 1991, had the peculiar title of "Leck mich im Arsch". In English, this translates to "lick me in the arse".
In modern terms, this would be equivalent to "kiss my ass!"
It's thought that this particular piece was intended to be used at private parties for Mozart's friends. However, thanks to modern technology, you can listen to the song below.
