Demi received generally favorable reviews from music critics, who complimented Lovato's vocal performance.
The album debuted at number three on the US Billboard 200 with first-week sales of 110,000 copies, and has been certified 2× platinum by the Recording Industry Association of America (RIAA).
"[9] On May 6, 2013, Lovato asked her Twitter followers to "unlock" the entire album by putting song titles in hashtags.
The book gives fans behind-the-scenes access to the singer, including never-before-seen footage and interviews.
She said, "This album I've had enough time to really reflect on personal experiences and look back at my life after having overcome a bunch of things.
Lovato described Demi as "good old American pop music", which was deeply influenced by her breakout single "Give Your Heart a Break" and she felt the "super catchy" lyrics as well as the beat of the song resonated with fans, which she wanted to further explore on the album.
[13] This is demonstrated on "Shouldn't Come Back" and "Warrior", which Lovato states are too personal to perform live, comparing them to a song from Unbroken entitled "For the Love of a Daughter".
[15] Billboard states that "Warrior" has Lovato declaring herself "a phoenix that has risen from all-too-public ashes", with emotional lyrics such as: "I've got shame, I've got scars, that I will never show/I'm a survivor, in more ways than you'll know".
[17] Stripped down piano ballads on Demi includes, "In Case", which contains lyrics about heartbreak and "Nightingale".
She referred to the writing process for the album as "therapeutic", further stating: "It helped me get rid of my demons, I am a warrior now.
[20] Jason Lipshutz from Billboard gave a positive review, saying that "the singer has a strong grip on her skills as a performer, but is still chiseling away at the formula that works best for her as an artist, and is unwittingly putting that self-discovery on display here.
"[1] Jon Caramanica from The New York Times also gave a positive review, saying that it is "[an] often impressive fourth album.
"[26] Melinda Newman from HitFix gave the album a B−, commenting "The problem with Demi is that too much of the music here is so generic that it could be any teen queen delivering these tunes."
"[28] Its opening acts included girl groups Fifth Harmony and Little Mix, as well as Cher Lloyd on select dates.
The tour covered 41 shows in total across North and South America, as well as Canada and Mexico, beginning in Vancouver on February 9, and closing on May 17 in Monterrey.
The tour would bring new opening acts, Christina Perri and MKTO, as well as playing shows in bigger venues, such as the Staples Center.
The tour began on September 6 in Baltimore, with the first leg concluding on October 27 at the Barclays Center in New York City.
The song was written by Mitch Allan, Jason Evigan, Sean Douglas, Nikki Williams, Aaron Phillips and Lovato and produced by The Suspex.
[45][46][47] The song, with its prominent EDM influences, covered new ground for Demi, who had been previously known for her pop ballad singles.
"Really Don't Care", featuring British recording artist Cher Lloyd, was released as the fourth single from the album on May 20, 2014.
Once released in May 2014, Lovato performed the song on the Season 13 live final of American Idol,[49] Good Morning America Summer Concert Series, Late Night with Seth Meyers, and the 2014 Teen Choice Awards.
