Britney's Dance Beat is a rhythm game developed by ART Co for the Game Boy Advance in 2002. It features five licensed songs from Britney Spears, alongside her photos and a video of a concert performance. Successfully clearing a song unlocks photos to fill in the tour book, and clearing all songs in Concert Mode awards the player a "backstage pass" which allows the player to watch a concert performance video.
Walgrey completes all songs in Practice and Concert Modes on the hardest difficulty and obtains every unlockable in record time.
