Calderón's travels subsequently led him to Miami, where he incorporated dancehall elements into his musical style. In 2004, his album titled "El Enemy de los Guasíbiri" was released. The album's production included a mix of several urban genres. Calderón claimed that he preferred the influence of these other genres due to his belief that Salsa had "become too corporate and too safe". Years after its release, Calderón stated that he had never approved the release of the "Guasibiri" album, which he claimed was rather a collection of old songs and that it should be left out of his discography as an unauthorized album. Following the release of this album, reggaeton gained more influence with several hip-hop producers in New York. Calderón continued working on several mixtapes, being featured in remixes of Usher's "Yeah", Fat Joe's "Lean Back", N.O.R.E.'s "Oye Mi Canto" and Akon's "I Wanna Love You", 50 Cent's P.I.M.P remix and also Tego featured Aventura's "We Got The Crown".
