Like My Worlds Acoustic before it, Believe Acoustic maintains the flow of Bieber product following a proper studio album.
It features eight acoustic versions of songs from Believe, as well as three new songs.
Studio musicians do most of the instrumental work, but Bieber is credited with some guitar on a couple tracks.
The playful side of Believe is not well-suited for earnest, stripped-down renderings.
Party anthems like "Beauty and a Beat" and lines like "Chillin' by the fire while we eatin' fondue," from "Boyfriend," seem silly when performed with the singer in serious artist mode.
Unsurprisingly, the material that required less of a transformation -- such as "As Long as You Love Me" and "Be Alright" -- fares better.
There's some appeal in the new songs: the destined-to-be-a-fan-favorite "Yellow Raincoat," the adequate "I Would" (which is not acoustic), and the sad post-breakup piano ballad "Nothing Like Us," the last of which was written by Bieber alone and seems quite personal.
