On 19 November 2002, Arjona released his ninth studio album, "Santo Pecado", preceded by singles "El Problema", which reached No. 1 on both the "Billboard" Top Latin Songs and Latin Pop Songs charts, and "Minutos", which reached No. 5 on the Top Latin Songs and No. 3 on the Latin Pop Songs charts. "Santo Pecado" became a commercial success, selling more than 300,000 copies just in Mexico (double Platinum), 160,000 in Argentina (quadruple Platinum) and 200,000 in the United States (double Platinum). In 2003 Arjona released "Lados B", his second compilation album, including songs that were "not so commercial", and that he wanted to give a second chance at radio airplay. The album contained songs from all his past studio albums. Critical reception for the album was mixed. Birchmeier noted that it was "a misleading entry point into Arjona's catalog." Despite this, the album received a Gold certification in Mexico.
