Trivia

 * In reality, the group name "μ's" was decided through a cellphone poll by fans, with voting taking place between October 30 - November 14, 2010. The nominated candidates were:
 * μ's
 * Otonokizaka Nonetto
 * Livestar!
 * Little Diamond
 * Otonokizaka Idol Club
 * In the anime, it is revealed that Nozomi decided the name of the group, naming it after the nine goddesses of music.
 * Despite the meaning of the group's name, μ's have performed four times without all nine members present in the anime. For instance, μ's performed with only three members in S1 Episode 1 and S1 Episode 3, seven members in S1 Episode 6, and six members in S2 Episode 5.
 * Other polls also determined the names of the mini idol units: Printemps, BiBi, and lily white.
 * Based on cellphone polls, the member with the most votes would be given the center position of the next music video. For example, Nico was the center of Natsuiro Egao de 1,2,Jump! (夏色えがおで1,2,Jump!) because she won a poll.
 * Polls also determine the idols' hairstyles and costumes for the music video.
