Demi Lovato's third studio album is the 19-year-old American singer's first release after time spent in rehabilitation.
As with Rihanna, a troubled period has given rise to new depth. This is reflected in some deeply personal, slightly dark numbers.
However, despite Lovato's new musical gravity, Unbroken is a well-balanced celebration of recovery - providing evidence of a return to her fun-loving, youthful form.
The party starts with the rock-pop opener, All Night Long, with Missy Elliott and Timbaland helping crank up the energy.
Lovato benefits greatly from guest artists throughout her album. Iyaz lends a smooth R&B feel to You're My Only Shorty, while Jason Derulo's efforts in the powerful duet, Together, work perfectly to show off Lovato's talent.
Lovato has successfully shed her Disney image, but now she has to work hard to stand out in the pop genre.
