With only a few weeks left until the September 3 premiere of "Camp Rock 2: The Final Jam" on the Disney Channel, fans can prepare by getting familiar with the tunes from the movie's soundtrack, out Tuesday (August 10). Not only is it chock-full of catchy pop tunes co-stars Demi Lovato and the Jonas Brothers are currently playing on tour, but with tracks written by the likes of Kara DioGuardi and Toby Gad, the album is sure to have fans dancing in their living rooms.

But while the entire album will please "Camp Rock" followers, it's the songs with the bigger heart that have deeper meaning for Lovato.

"I'm really excited for fans to hear pretty much all the songs. A lot of the songs are really fun and they're dance songs, but there's also songs that are kind of emotional," Lovato told MTV News at tour rehearsals. " 'It's Not Too Late,' I really enjoyed singing it. I loved performing it," she added. "And also 'Wouldn't Change a Thing' is a song that's really fun to perform because I really get to showcase my voice."

Of course fans will enjoy hearing "Wouldn't Change a Thing," if only because it reunites Lovato and Joe Jonas — on record, at least. "Yeah, it sounds really great [performed live]," she said. "And it's fun too. We're having a good time with it."

Although the "Camp Rock 2" soundtrack songs aren't official Lovato tracks, the singer said she works hard to get into the right headspace to interpret the songs. And she loves singing, which makes it a lot easier.

"You know, not all of the songs are emotional because it's a Disney musical movie, so we like to keep it really upbeat, especially when it's aged towards a younger demographic," she explained. "Kids lose interest, so you have to keep it upbeat, but sometimes there are times where we pay more attention to the older crowd and one of the songs being 'It's Not Too Late.' Even though it's not my song that I wrote or even that's going to be on my album, I'm able to put my personal experiences into it.

"I really enjoy singing, whether it's my own songs or other people's songs."
