mellow guitars are a welcome change from the squealing synths and pounding beats favoured by Bieber and his peers," and that the album had the ability to connect with audiences beyond his demographic. Mikael Wood of Entertainment Weekly gave the album a "B−" rating, stating that the album doesn't change Bieber's beloved "kiddie-soul vocals" calling it "perfunctory", but said that acoustic renditions such as "Baby", "One Time" and new song "Pray" deliver their "saccharine payload." Thomas Conneron of Chicago Sun-Times said that "calming down several of the pop tunes with slower tempos and patient singing" was not bad and that slowing everything down made listeners hear how the singer's voice had matured. Calling it "the sugariest acoustic album in history," Allison Stewart of The Washington Post said "its arrangements and melodies – the best parts of any Bieber record - are stripped down but otherwise little changed, demonstrating just how great most of these songs were to begin with." Stewart also said that urban numbers such as "Baby," "survive their makeovers without a hitch." Andy Kellman of Allmusic gave the album 2 and a half out of 5 stars saying that the album was "an enticement." Dan Savoie of Rockstar Weekly gave the album 4 out of 5 stars, saying that it is "the perfect showcase for a talented young artist who's on his way to the Grammy Awards this year." Although she commented that the "acoustic" labeling was a bit misleading, Monica Hererra of Billboard said that the album "succeeds", calling songs like the live version of "Favorite Girl" the album's saving grace and "truly acoustic." On the former, Herrera said, "It's the one moment where you can hear all of the young artist's strengths falling in line-raw talent, maturing vocals and, of course, an all-too-valuable connection with his fans."
