With its air-light melody and supercharged youthful vigor, A * Teens' "Bouncing Off the Ceiling (Upside Down)" could be this years "MMMBop," a pure pop pastry that's so infectious that its appeal could spread beyond the act's traditional Radio Disney core. As with the Brit foursome's previous efforts, a sound reminiscent of Abba is at the heart of the matter, with sunny female vocals and a giddy-up beat leading the charge. One listen is all it takes for the chorus to bore its way into the brain, leaving even the most jaded top 40 listener prey to its charms. The accompanying videoclip-included on the song's commercial single-adds all the more appeal, showcasing members Amit, Sara, Dhani, and Marie as fun-loving, would-be teen idols. This is quite the guilty pleasure and a track that could click at top 40 with the proper promotional push. It glows with innocent charm.
