Initially set for a December 2, 2008, release, the album was pushed up to November 28, 2008.

María José was released on November 26 because of the finishing of the album earlier than expected.

The album is mostly a cover album, covering four of her songs performed on Latin American Idol, but it has two tracks that were written for Castillo and her partner Margarita Henríquez.

But later on December the album got more promotion on other countries, and the sales got higher.

The album has been very successful for Sony BMG Latin America, on December 8, 2008, Sony BMG announced Castillo and the public that the album had sold 5,000 and got a Gold Certification.
