I like The GIFT but I do think it is one of the safest songs she ever released. It's a nice pleasant ballad but it felt a bit bland for Ayu. But AUDIENCE I simply love. I never get tired of it. It's so fun and full of energy.
As for the 10 year anniversary of Ayu's 2010 activities, I also feel so old. The whole 2020 new year, new decade has me feeling mind blown about how much time has gone by.
