### "Ab dance"

One month after beginning promotions for the song "A", the "belly dance" or "ab dance" featured in the music video and choreography of the song was banned from broadcast and rated +19, due to being "too sexually suggestive". The girls slowly lift up their shirts to expose their stomach in the choreography. Despite the controversy, the song was released in Japan on September 14, 2011 as their Japanese debut single.
