Endorser is an English loanword used in Italian, referring to someone who publicly supports or promotes a product, brand, or idea.
In the song, Salmo uses it in a provocative and ironic way: "E se l'odio fosse una marca farei sicuramente l'endorser" (And if hate were a brand, I would definitely be the endorser). This line is striking because it personifies hate as a marketable product, and the artist positions himself as its promoter, highlighting a cynical yet compelling perspective on modern society and his own artistic identity.
"Il Senso Dell'Odio" is Salmo looking back at a life full of "should have, could have, wanted to" and turning that regret into fuel instead of letting it sit. He talks about the fear of waking up with no clear "next," the nights he never came home before three, and the version of himself that skipped school and dreamed, half seriously, of a normal university life instead.
The title line is the key: he says he "loves the sense of hate, corroded," almost proud that he'll never be conventionally famous, because in Italy fame just means how much you sell, and that's not the game he's playing. He'd rather write.
The chorus turns that bitterness into something almost hopeful. "All that's left is hate when everything ends, you'll still find me here" isn't despair, it's defiance: as long as you can still feel something that sharp, you know you're alive. He wishes he could rewind time like the internet legend John Titor, just to live it all the same way again, mistakes included.
By the end he widens the lens to his whole city: half the people around him feel exactly what he feels, but nobody can put it into words. Writing, for him, is what finally does.
