Jesto's song Nella Mia Testa RMX is about not being able to enter into his mind. He wants to celebrate as if it's his party and creates a world on his note cards. He talks about his crazy world and the files that are protected. He has never had successful projects in his life and disconnects from the truth online. He is against envy and resentment and expresses his honest thoughts. He hopes alcohol will disinfect his mind, but it doesn't seem to work. He turns off the TV and turns to himself, as he cannot recover from pressing the recovery button. He doesn't have problems and instead, problems have him. He plays with rhymes and takes public transportation like a joke. He is playful in public and serious in private. He has been waking up irritated for years, and it shows in his music. The overall theme of the song is that Jesto has a unique perspective that cannot be easily understood or penetrated by others. He creates his own world and has no interest in conforming to others' opinions or beliefs.
