[2] It is a cover album consisting of Nina's renditions of familiar love songs written by American songwriter Diane Warren.

[3] The idea behind the release of the album started after the success of her single "I Don't Want to Be Your Friend" in 2004, which was initially recorded for Warren's love songs compilation.

Despite criticisms, the album proved to be a commercial hit, certifying Gold by the Philippine Association of the Record Industry (PARI) on September 1, 2008.

In 2004, Warner Music Philippines came out with a compilation of Diane Warren's all-time hits, on which Nina contributed a song—"I Don't Want to Be Your Friend".

In a press conference on July 29, 2008, at Red Box, TriNoma in Quezon City, Nina revealed that she is a fan of Warren, and that she wanted to do a record consisting of her hits.

A message by Warren, stating "A few years ago Nina cut "I Don't Want to Be Your Friend", one of my favorite songs.

[4] Bobby Velasco, Alvin Nunez, producer Ferdie Marquez, Mike Luis of Freestyle, Jay Durias of South Border, and Nina's band were assigned to re-arrange the songs.

Despite certifying Gold just a week after its official release, Nina Sings the Hits of Diane Warren received very few nominations on awarding events and negative response from OPM critics.

"Love Moves in Mysterious Ways", the album's first single, became very popular in the Philippines that even though the song was just a cover, it was considered as a Nina hit.

"I Don't Want to Miss a Thing" was released as lead single, alongside Nina Sings the Hits of Diane Warren in August 2008.

Nina's rendition of the song was initially compared to Regine Velasquez's R2K (2000) version, which consisted mostly of high notes and vocal belting.

Due to its completely different arrangement, Nina's whispery, toned-down mellow version eventually made its own impact to Filipino listeners.

In early 2009, "Saving Forever for You", a song originally recorded by Shanice, started receiving heavy airplay on TV and radio.

Nina Sings the Hits of Diane Warren was officially launched on July 29, 2008, at Red Box Karaoke, TriNoma, Quezon City.

On August 18, 2008, Nina guested on a Boy & Kris episode, "Birit by Request", with Christian Bautista and Lani Misalucha.
