it's hard to tell because NINKI are always 99.999% off the mark
I'm sure a lot of YUI fans have been anticipating her comeback since she hasn't release an original album for 2 1/2 years so we'll see
She will be performing Please Stay With Me next Fri on MUSIC STATION
1) SMAP - We are SMAP!
2) BREAKERZ - Gekijou
3) Hey! Say! JUMP - Special Medley
4) Becky - Emerald
5) YUI - Please Stay With Me

guess it's safe to say that Please Stay With Me is the main promo album track , like what happened for Laugh away too in I LOVED YESTERDAY
