El Disco Duro

El Disco Duro (Spanish for "The Hard Disk") is an unreleased and later cancelled studio album by Puerto Rican rapper Daddy Yankee. It was originally scheduled to be released during early 2017 under its original title King Daddy II: Elemento DY, a sequel to his previous album King Daddy, produced by Los de la Nazza, a production duo that worked with Daddy Yankee from 2007 to 2014. The album was to include "Sígueme y Te Sigo", "Dura", "Vaivén" and "Shaky Shaky" as singles, which were released between March 2015 and April 2016.

Background
El Disco Duro (originally titled King Daddy II: Elemento DY) was going to be the sequel of his previous mixtape King Daddy, released in October 2013, which became the first digital-only Latin album that managed to rank within the top 10 on the US Top Latin Albums chart. Two months after the release of King Daddy, Daddy Yankee announced that there was going to be a physical version of the album, with exclusive bonus tracks, planned to be released during 2014, but it was not published after all.

The Puerto Rican production duo Los de la Nazza, which had been working with Daddy Yankee since 2007, left El Cartel Records and stopped being his main producers in order to focus on their careers. Chris Jeday and Gaby Music were hired as the album's main producers during late 2014. El Disco Duro was officially announced during mid-2014 as King Daddy II with the promotion of the single "Sábado Rebelde" featuring Puerto Rican duo Plan B, released on October 31.

On September 10, he was urgently moved to a nearby hospital in Cali, Colombia, where he was set to perform later that night. Daddy Yankee suffered a rise in blood pressure, hypoglycemia and dehydration, which almost caused him to suffer a heart attack before being treated by doctors. His condition improved and he was sent to rest in his native Puerto Rico, but had to cancel other concerts in Colombia. On October 19, he confirmed that his hypoglycemia worsened and turned into a prediabetes.

In January 2017, he was featured on the reggaeton-pop single "Despacito" by Puerto Rican singer Luis Fonsi. The song was a worldwide success, topping the charts of 45 countries, including a number 1 spot on the Billboard Hot 100, the first for a primarily Spanish-language song since "Macarena" by Los del Río in 1996. The success of the song led Daddy Yankee to become the most listened artist worldwide on the streaming service Spotify on July 9, 2017, being the first Latin artist to do so.

In March 2017, Daddy Yankee announced a global partnership with Zumba Fitness, in which he would record exclusive tracks for the Zumba Instructor Network. On March 15, 2017, Daddy Yankee was recognized as Artist/Songwriter of the Year by the American Society of Composers, Authors and Publishers during the 25th Annual ASCAP Latin Music Awards. A day later, he received a Puerto Rican Walk of Fame Star in San Juan, becoming the first urban act to do so.

Composition
"Sígueme y Te Sigo" is a dance love song written by Daddy Yankee, Chris Jeday and Luis "Wichi" Ortíz Rivera, inspired by social networks but not centred on them, and mixes reggaeton with Latin pop, including an electric guitar riff.

"Vaivén" is a moombahton song written by Daddy Yankee, Luis "Wichi" Ortíz Rivera and the producer Chris Jeday.

"Shaky Shaky" is a reggaeton song born as a freestyle during early December 2015, and was later recorded by the production duo Los Evo Jedis. According to Daddy Yankee, the main vocals were recorded in one take and the song musically mixes sounds from old and new school reggaeton. The keyboard bass line was based on the one from the single "Murder She Wrote" by Chaka Demus & Pliers, released in 1992. It also includes a repeating sample of a horse's neigh from Mel and Tim's "Good Guys Only Win in the Movies" (1970), which became popular after Cypress Hill's "Insane in the Brain" (1993).

"Otra Cosa" features Dominican singer Natti Natasha and is a fusion between reggaeton, dancehall and moombahton music written by Daddy Yankee, Natti Natasha and Puerto Rican producer Haze. The lyrics are about lovesickness. The concept of the song was brought to Daddy Yankee by Haze and Natti Natasha in order to be included on the track listing of La Super Fórmula, a Pina Records studio album by various artists.

"La Rompe Corazones" features Puerto Rican singer Ozuna and was written by Daddy Yankee, Ozuna, Chris Jeday and Puerto Rican songwriter Jesús "Benny Benni" Benitez Hiraldo. The song tells the story of a lovesick woman who no longer trusts her relationships, taking revenge on other men through her frustration.

"Dura" is a Reggaeton song released on January 18, 2018. "Dura" and its music video, directed by Carlos Pérez, filmed in Los Angeles and based on 1990s style and visuals. The song was written by Daddy Yankee, Juan Rivera, Luis Romero, and Urbani Mota, and was produced by Los Evo Jedis. A remix version featuring Becky G, Bad Bunny and Natti Natasha was released on April 27, 2018.

Production
The first known recording session for El Disco Duro with producers Chris Jeday and Gaby Music was held in December 2014. The last known session was carried out in May 2017 with the recording of the track "Percocet". The recording was resumed during mid-October 2016 with Daddy Yankee and Dominican singer Natti Natasha recording the single "Otra Cosa" for Pina Records' upcoming studio album La Super Fórmula. However, Daddy Yankee managed to include the track on El Disco Duro during December 2016. On February 21, 2017, Daddy Yankee uploaded an image on his official Instagram account listening to the album.

Studios where the album was recorded includes Daddy Yankee's El Cartel Studios in Santurce, San Juan, Puerto Rico, Chris Jeday's Music Capos Studios in Puerto Rico, Criteria Studios in Miami, Florida, USA, and Master House Studios in Doral, Florida, USA.

"Sígueme y Te Sigo" was mixed at El Cartel Studios in February 2015. Sound test for "Vaivén" was held by Chris Jeday at Music Capos Studios during early August 2015. The song was later mixed at Criteria Studios and at El Cartel Studios the same month.

Release
Daddy Yankee confirmed on October 26, 2016 during a meeting with Zumba fitness creator Beto Perez at Pina Records that El Disco Duro will be released during early 2017, most likely during January or February. On June 21, 2017, Daddy Yankee stated that he postponed the album's release due to finding more successful the release of singles instead of an entire record. In December 2014, Billboard magazine added digital and streaming information to count sales: 1,000 digital songs sales and 1,500 song streams separately equal one album sale, which may affect the chart placement of the album. Considered on-demand audio services includes Spotify, Google Play, Beats Music and Xbox Music.
