Britney's Dance Beat for the Game Boy Advance is a decent music-inspired video game, but it's definitely less about music and rhythm than it is a platform to promote Britney Spears herself.
In the game, you assume the role of Britney as she prepares for her upcoming world tour. Using various combinations of the A, B, and directional-pad buttons, your onscreen persona will flail and dance in time with five popular Britney Spears songs. The songs include "...Baby One More Time," "Oops!...I Did It Again," "Stronger," "Overprotected," and "I'm a Slave 4 U."
While the motion-captured visuals are superb--especially for a handheld system--the overall screen layout and gameplay don't lend themselves to sightseeing. As your dancer twirls and shimmies in the center of the screen, you'll find yourself paying more attention to the dizzying step indicator at her left. During the song, it rotates in a clockwise direction and highlights the appropriate dance steps, which you're supposed to perform by pressing the designated button combination.
Dancing is easier said than done, as the step indicator spins far too fast in the practice mode and at near supersonic speeds in the concert tour mode. The button combinations that appear within the step indicator, while random, at least fit the overall pace of the music. Unfortunately, the appearance of contradictory directional arrows, combined with a rapidly rotating indicator, creates an interface that is somewhat confusing and, at times, nauseating. The game would have been better served by a more traditional horizontal or vertical timing display.
