Verdena's songs are always sung in Italian, with the exception of some covers, such as ("Reverberation" by 13th Floor Elevators, "Sunshine of Your Love" by Cream), "(His Latest Flame) Marie's The Name" by Elvis Presley, "Harvest" by Neil Young and "Creepy Smell" by Melvins), as well as an original song called "Perfect Day". The meaning of the lyrics is often obscure due to the made-up language the song is sung in. Within the lyrics are references to Smashing Pumpkins, Nirvana, and Fecal Matter (the title of "Il Suicidio Dei Samurai" is a reference of "Samurai's Suicide").
