This page serves as the official song center page for Nijigasaki High School Idol Club, which are indicated via Love Live! School Idol Festival ALL STARS. Only official confirmations which come directly from the staff, the members of each group, or the above source are listed below. Note that the performance of a song in the anime or other PV is not considered a documented reference unless it explicitly states that there or there isn't a center for the song.
It should also be noted that centers in ALL STARS have been subject to change and have in some cases been inconsistent with other confirmations of centers. Nevertheless, it is currently taken as a confirmation unless other official references says otherwise. In particular, it has this discrepancy:
Songs whose centers have changed in updated releases onto ALL STARS (e.g. Sing & Smile!!, Kakushiaji!) have appeared to use "placeholder" centers in their previous releases. While songs with changed centers cannot be positively identified as having had placeholders, it has been strongly implied, as the majority of these songs had been recently released, never been performed at the time of their release, and/or use the default cast order number for their formation. This may possibly occur as a result of the formation or center of the song having been undecided or unrevealed, and a placeholder center being required for game balance purposes in ALL STARS (as the centers(s) have certain benefits over other members).
