The song "Mostri" by Letizya talks about a road trip with someone who was once a significant other. The lyrics convey the feelings of missing the city and traveling the world in the mind, while feeling the absence of the person who used to be by their side. The song also reflects on the realization that the person is not who they used to be, as they no longer walk with their head held high and hands in their pockets, and no longer help in conquering the struggles and fears. There are also mentions of exchanging ugly words, but they no longer hurt, as only the person being addressed understood the world of things to be said. The overall message of the song is about coming to terms with the changes in a relationship and the sense of loss and acceptance that comes with it.
