Trivia

 * During the early months of the project, the group was actually named "Love Live!". This was before any concrete plot had been conceived yet.
 * 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 Season 1 Episode 1 and Season 1 Episode 3, seven members in Season 1 Episode 6, and six members in Season 2 Episode 5.
 * Other polls also determined the names of the mini idol units: Printemps, BiBi, and lily white.
 * Based on 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.
 * For some music videos, polls also determined the idols' hairstyles and costumes.
