Abraham announced the album through an interview with San Antonio-based Latin Groove News on March 10, 2022. The album has been completed, though it was being
remastered while the artwork was being handled by Suzette, at the time. In April 2020, A.B. revealed that their mother, Marcella Quintanilla, had originally selected the artwork for the album before it was postponed due to the
COVID-19 pandemic. According to Abraham, this album has been long-awaited by fans of the singer and believed it will be received positively by the public. News of the album's release sparked criticism from fans who believed the album would not be authentic, while others questioned the family's motive for releasing the album believing they "are profiting off [of Selena's death]". Abraham responded that he is aware of their criticisms and believed that those who are critical of the album are unaware on the
recording contract that the family made with Selena prior to her death. Abraham has received negative comments from fans since Selena's death; he initially found her fan's criticisms hurtful, though he now says that the negative comments he receives no longer bother him. EMI Latin has released a plethora of posthumous albums, as well as unreleased material by Selena since her death. Suzette stressed that the preservation of Selena's legacy through her works has been a difficult task that has made it harder for the family in coping with the singer's absence. A.B. recalled a phrase Selena would often say: "The goal isn't to live forever but to create something that will" when interviewed by a reporter for
La Prensa Latina on the negative responses the family has received. Biographer Joe Nick Patoski, called the commercialization of Selena a business, saying that "it happens when your father is your manager".
WOAI-TV called comments such as "just let her die" and "let her go, she's dead" that were left by people on their Facebook posts on Selena, as seemingly insensitive. Matt Wille of
InPut Magazine, believes that positive responses by fans depend "greatly on the care" the family incorporates in the recordings. Critics have questioned the ethics involved in creating the album. Wille questions this in the involvement in the computer manipulation of a singer who has died saying the "conversation is much less clear-cut", in comparison to living musicians who use this technology, he also questioned whether or not Selena would have approved of this album. This concern was echoed by Craig Huber of
Spectrum News, who found the idea of updating a 13-year-old Selena song both "interestingly, and perhaps controversially". In a poll conducted by
The Today Show, 57% of participants believed that unreleased songs by Selena should not be released with a digitally updated voice, while 29% believed that there is no harm in doing so, 14% were neutral or had no opinion. Stella Chavez of
National Public Radio (NPR) took to Twitter to complain about the new release disliking the idea of Selena's voice being "done using computers". Suzette Exposito of
Rolling Stone magazine, also took to Twitter to criticize the release writing that "nothing is stopping Selena's family from working with new artists today". According to
Joe Bennett, a forensic musicologist and professor at
Berklee College of Music, the ability to digitally age Selena's voice is "a simple process" that he believes "could potentially require just an isolated recording of the singer and the appropriate digital software." A journalist for
The Los Angeles Times, called the project "a Selena robot album" that the singer wouldn't have wanted. In their response to critics, A.B. and Suzette agreed that if Selena were alive, she would have been overjoyed of
Moonchild Mixes. Suzette believes in tuning out critics, "what critics? We don't care about them", as she later puts it. She finds that "as an artist and musicians and people that are in the public eye" need to find a way to ignore those who oppose them. She explained that her family will continue "to do what we want with our music, with our sister, with our band", though they want people to understand their projects for Selena have been done "with loving care and with beauty." A.B. disagrees with the notion that the family is taking "advantage of Selena's legacy", saying that "what we're doing is honoring her memory, her legacy. That's what it's about". == Track listing ==
