Uccidersi d'amore is a dramatic Italian expression that literally means "to kill oneself for love". It's a powerful hyperbole used to describe being completely and utterly consumed by romantic feelings.
In the song, the singer recalls his past self, a player who would never get tied down. He asks rhetorically, Uccidersi d'amore, ma per chi? ("Die for love, but for whom?"). This makes it deeply ironic when, in the chorus, we find him completely captivated by a new love, unable to think of anything else.
Come Mai is a catchy pop confession in which the Italian duo 883 and Max Pezzali paint the dizzy feeling of falling head-over-heels in love: sleepless nights melt into dawn as the singer drags melodies and memories home, scribbling kilometre-long letters just for the chance to see her again; once the self-assured friend who never stopped, he now waits alone in his room, praying for a single “yes,” stunned by how this mysterious girl has turned his rational world into a daily battle with emotion; the chorus’s repeated question, “Come mai?” (How come?), captures the mix of wonder, disbelief, and vulnerability that erupts when love arrives unannounced, proving that even a supposed “almost god” can be reduced to a hopeful dreamer by one unexpected heartbeat.
