According to ESRB, this game contains: Lyrics, Suggestive Themes

Parents can rest assured that none of the songs contain any explicit lyrics. As with most pop/dance music, the words can be a tad suggestive at times. However, there's nothing particularly offensive here, unless of course one is easily offended by mediocre dance music.
Fans of karaoke and rhythm/dancing games will probably be disappointed by the game's loose controls, imprecise audio syncing, and shoddy microphone. Players seeking a karaoke or rhythm game fix would do well to look elsewhere.
Carpal tunnel sufferers should know that the repetitive controller swinging that is required for this game can cause significant wrist soreness.
HDTV owners will appreciate the presence of both 16:9 widescreen and 480p progressive scan, the latter of which only works with Wii component cables.
Deaf and Hard of Hearing gamers could theoretically play the dance sections by following the onscreen beat indicator. The karaoke, however, requires the player to sing the correct pitch and therefore would be almost impossible for this group of gamers to play.
