SO, it turns out: Mozart was a funny mother-fucker. In addition to his symphonic victories, he wrote this little beauty, called "Leck mich im Arsch" - or "lick my ass". You can hear it hither:
Here are the lyrics to his second song "Lick my ass nice and clean":
Lick my ass nicely,
lick it nice and clean,
nice and clean, lick my ass.
That’s a greasy desire,
like the licking of roast meat,
my daily activity.
Three will lick more than two,
come on, just try it,
and lick, lick, lick.
Everybody lick his own ass himself.
I dedicate this song, to Monday.
