sbatti is a very common Italian slang word that you won't find in a textbook. It's the plural form of sbattimento and means 'hassles', 'bothers', or 'annoyances'—all the tedious things you don't feel like doing.
In the song, Angelina Mango sings about wanting to "rimandare gli sbatti" (postpone the hassles) to enjoy a sweet, carefree day with someone special. Learning 'sbatti' is a fantastic way to sound more like a native and understand the casual, modern Italian used in everyday life.
This song is the ultimate anthem for putting off your problems and just living in the moment. Angelina Mango sings about wanting to escape the stress of city life, where even advertisements on a tram feel like someone's eyes watching you. She'd rather enjoy a "Domenica dolce, che dolce far niente" (sweet Sunday, how sweet it is to do nothing) with someone special than deal with "tutte quelle storie tristi" (all those sad stories).
The whole feeling is about letting go. If a problem comes up, just let it slide away "Come una macchina sull'Autostrada del Sole" (Like a car on the Highway of the Sun). The chorus is a perfect summary of this carefree attitude: "Male che vada / Ci pensiamo domani" (If worst comes to worst / We'll think about it tomorrow). It's a fun, rebellious song that even says it's beautiful to make mistakes, so why worry? Just enjoy the here and now.
