In "Galería Caribe", Arjona explored Afro-Caribbean sounds, employing traditional rhythms such as guaracha, bachata, merengue, and salsa. On "Santo Pecado", Arjona explored the use of symphonic sounds on his ballads, amidst a couple of rock songs stylistically similar to those on "Sin Daños a Terceros". This album included the song "La Nena (Bitácora de un Secuetro)", in which Arjona relates the story of a girl who is kidnapped by her uncle. Then, in 2005, Arjona adopted new sounds in "Adentro". Gutierrez considered the instrumentation, performance, and overall sonic palette to be "minimalist" and "unassuming". On this album, Arjona included more Latin sounds, Mexican and Tejano music on "Mojado", a song about immigration; merengue and Colombian tones on "Adiós Melancolía", and some on "No Te Cambio Por Nada".
