He confirmed his reputation with the release of his fifth studio album, "Historias". The album sold 2 million copies throughout Latin America and received twenty-seven platinum and two diamond certifications, including quadruple Platinum in Argentina. "Historias" reached No. 43 on Top Latin Albums and included the hit singles "Te Conozco" (No. 3 on "Billboard" Latin Songs) and "Señora De Las Cuatro Décadas" (No. 7 on Latin Songs). The Allmusic review by Jason Birchmeier awarded the album 4.5 stars stating that "If you were to pick only one Arjona album for your collection that wasn't a greatest-hits compilation, this should be the one. "Historias" was a career-defining success for Arjona." His fourth and fifth studio albums were the best-selling of his career.
