My Worlds: The Collection is the first compilation album released by Canadian recording artist Justin Bieber. As the international alternative to the Walmart and Sam's Club exclusive My Worlds Acoustic (2010), My Worlds: The Collection was released in numerous European countries on November 19, 2010. The album consists of two discs; the first is a slightly altered version of My Worlds Acoustic, and the second is My Worlds, a compilation itself made up of My World (2009) and My World 2.0 (2010). In addition, the album also features a new song, an inspirational ballad entitled "Pray", a Jaden Smith collaboration, "Never Say Never", and remixes of "Somebody to Love". The new versions of the songs were produced by Bieber's music director, Dan Kanter, his vocal producer Kuk Harrell, and also producer Rob Wells. While most reviewers complimented the set, several thought that its release was unneeded. The album charted moderately in Europe, reaching the top half of several album charts.
The first disc includes songs from My Worlds Acoustic, which features acoustic version of songs from Bieber's debut extended play, My World, and his first studio album, My World 2.0. Bieber spoke with MTV News and he wanted to record the acoustic songs for the "haters" who say he cannot sing and saying his voice was auto-tuned, and that "stripping it down and having it kind of really mellow and being able to hear my voice" was his purpose. The singer said he wanted to do the acoustic set because the production sometimes "drowns out your voice" and "takes away from the singer, over the synths and everything." In addition to the acoustic tracks, the first disc also contains the Usher-featuring and J-Stax remixes to "Somebody to Love", the single version of "Never Say Never", featuring Jaden Smith, as well as a new song, an inspirational ballad entitled, "Pray". The second disc features songs that were present on My Worlds, a package of My World and My World 2.0, which was released instead of or in conjunction with My World 2.0 in select international countries.
According to Bieber, "Pray" is a gift to his fans. The song's arrangement is set to reflect Bieber's music before he was discovered, but also includes instrumentation from a string quartet, congas, and a cajon drum, the latter to represent Bieber's worldy travels, specifically to Africa. While Bieber was being interviewed by Ryan Seacrest on his radio show, Bieber talked about the song's initial writing stating the song was influenced by Michael Jackson, and he thought of Jackson's "Man in the Mirror" when writing the song. Vocally, Bieber's vocals are sung in a lower key compared to previous singles. Bieber plays guitar on the acoustic versions, along with his guitarist and musical director Dan Kanter. The acoustic versions of the songs were produced by Kanter, Bieber's vocal producer Kuk Harrell, and also producer Rob Wells.
The album was released on November 19, 2010. "Pray" was released as the album's first and only single on in select international countries on December 3, 2010. It charted moderately, reaching number sixty-three in Austria, fifty-one in Germany, and appeared on the Tip charts in Belgium.
The compilation received mixed reviews from critics. Andy Kellman of Allmusic gave the album four out of five stars. Although Lucy Jones of The Daily Telegraph said the album seemed as something else to be "cashed in on", she called the collaborations "perfectly polished", and gave the album four out of five stars. Hermonie Hoby of The Guardian said that "regifting" following his past two releases seemed unnecessary, but noted that "the billion or so Beliebers" wouldn't feel "churlish."
