I think it was okay, not bad at all but not
the best. t2m was great.
And I love i.e. decision and untitled ~for her~ but Ladies Night and Rainbow weren't so great
And about this Peco&Princess problem, they've been her backup singers for years now so I think Ayu should already know how's their singing, but yes it sounds at times like their mics are set louder than Ayu's and that's when Ayu can't really sing well over their voices.. >__>
