"Anal Beat"
"Mi abbandono ad un ritmo ancestrale,
Sotto un cielo australe entri in me per via rettale"
TRANSLATION:
"I abandon myself to an ancestral rhythm,
Under a southern sky you enter me rectally"

"50 Bocca/100 Amore"
"Il tempo passa come una brezza, la giovinezza
Mi sento vecchio, mi guardo allo specchio
Ti faccio un pompino, ma in motorino"
TRANSLATION:
"Time passes like a breeze, youth
I feel old, I look in the mirror
I'll give you a blow job, but on a motorbike"

"Il Sesso Vende Sempre" ("Sex Always Comes")
"La noia mi assale
Ma troverò l’unico Dio in cui crederò
A anche se il sesso e' sempre lo stesso
Un orgasmo mi darà la mia felicità"
TRANSLATION:
"Boredom assails me
But I will find the only God I believe in
And even if sex is always the same
An orgasm will give me my happiness"
