This Wal-Mart exclusive CD includes a bonus track "Take It To The Maximum" by J Prima, ringtone and wallpaper.

Everybody knows about the Bratz dolls phenomenon. Those sassy little chicklets are the Barbie dolls of the decade. The original four dolls became so wildly popular that spin off lines of other Bratz dolls, as well as animated DVDs, started rolling out at a crackling pace. Then 2007 saw the release of the Bratz movie, featuring flesh-and-blood characters and spawning this stirring 21-track soundtrack CD.

With the Bratz brand already consolidated, a feature film was a no-brainer. Consequently, the soundtrack ripped up the charts, impacting the Billboard 200 albums chart and flying all the way to No. 7 on the magazine's Top Soundtracks chart.

The song selection here is at once diverse and totally fitting. From rock to rap to pop and beyond, it captures the spirited essence of what the Bratz fad is all about. "Rock Star" by Prima J -- a duo of cute young women who are also cousins -- really gets things rolling with its bumping beat and mix of rapping, singing, and rocky, throaty guitars. While working within the parameters of pop, the album starts pushing the boundaries in all kinds of directions from the outset.

Jamaican-born sisters Nyanda and Nailah Tharbourne, aka Brick & Lace, may take you to the Caribbean with their number "Love Is Wicked," but that doesn't mean that the Slumber Party Girls can't bring on the blink-182-esque punk-pop stylings of "My Life." And a touching, strings-and-piano ballad like "Rainy Day" by Janel Parrish can slot right in with a mid-tempo rocker (think Sheryl Crow) like "Now or Never" by Orianthi that boasts some wild guitar licks.

Variety is not a problem here. Neither is passion or momentum. The positive energy reflects the whole Bratz sensibility perfectly. And fans of the phenom will totally key into a song like "It's All About Me" by Chelsea Staub with its references to MySpace, cell phones and texting.

Want a little boy band with your Bratz? Check out "Heartburn" by NLT. Some hard-soft alt-rock? That would be "Tell Me" by Dropping Daylight. A taste of synthed-up, floor-filling pop? Then don't go past "Fabulous," also by Chelsea Staub.

There's all that and much more on the Bratz soundtrack. This disc is energizing: no downers will be admitted. And while it is targeted at a younger audience, there are some cuts here for most age groups. After all, you're never too old to let the brat in you come out once in a while.
