The song encourages everyone to rock their body to the music of Backstreet Boys, who declare that they are back again with their signature sound. It asks a series of rhetorical questions to assert that the band is original, unique, and everything their fans need. The lyrics tell listeners to not be afraid and that as long as there is music, Backstreet Boys will keep performing and coming back for their fans.
