Just noticed - I think the fan means the Budokan live Love & Songs from 2012, cause the Billboard live was fully called Eternity ~Love & Songs~ like the cover album.
And if you look at the medley:
Step Into My World ~ Got To Be Real ~ECSTASY ~ 走れ!~ You're So Beautiful are all songs from the UNIVERSE Tour setlist, while 愛のことば~Rain ~POP DIVA were performed at the Budokan Love & Songs live.
UNIVERSE and Comes Up were performed at both.
Those must be results from the FC voting, cause the only question they didn't publish the results for in the last FC magazine was the one about the favourite live.
