Camp Rock 2: The Final Jam, with Lovato reprising her role as Mitchie Torres, premiered on September 3, 2010.  Critics were ambivalent about the film's plot, and it has a 40-percent approval rating on Rotten Tomatoes.  However, Lovato's performance was called "dependably appealing" by Jennifer Armstrong of Entertainment Weekly.  The film premiered to eight million viewers, the number-one cable-television movie of the year by the number of viewers.  Its accompanying soundtrack was released on August 10 with Lovato singing nine songs, including "Can't Back Down" and "Wouldn't Change a Thing".  The soundtrack debuted at number three on the Billboard 200, with first-week sales of 41,000 copies.  The Jonas Brothers Live in Concert was reworked to incorporate Lovato and the rest of the film's cast; it began on August 7, two weeks later than planned.  The Sonny with a Chance soundtrack was released on October 5; Lovato sang on four tracks, including "Me, Myself and Time".  It debuted (and peaked) at number 163 on the Billboard 200, her lowest-selling soundtrack.
