This is what I wrote about the normal edition:
OK, Miley Cyrus has connections in the music business and Selena Gomez is really pretty, but Demi Lovato is the only Disney starlet of this generation to have talent. She writes her own songs, though on this album she did have help as she admits that what she writes is more hard rock and such an album wouldn't sell - at least under a Disney label (we're still waiting for it Demi!), but still she did a lot and you can see that she is singing her own songs, it's just more natural. She also has a voice, which she has shown (and stunned the audience) some time ago singing the US Nationa Anthem at an important sporting event. Here she doesn't use it all that much (though more on the Platinum Edition!) but you can still she that she's got it. And last but not least, this is the only Disney star album that can really be called pop-rock with emphasis on the rock part. We see some nice guitar playing and not the usual pop-dance eletronics or the newly popular country-styling.
But the Deluxe Edition gives you more. Three extra tracks of really good quality, with the last one, roughly an accustic remix in Spanish of the song This Is Me from Camp Rock showing Demi's voice and ability to sing in Spanish. The DVD is also a nice touch, though I was never into such additions, however this edition is worth it for the extra tracks.
