Trivia

 * In reality, the group name "μ's" was decided through a cellphone poll by fans, one month after the release of their first single Bokura no LIVE, Kimi to no LIFE (僕らのLIVE,君とのLIFE) in August 2010.
 * 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.
