As with others have said, I loved Exodus from the offset. It's one of my favourite albums, tied with Ultra Blue (I've always loved Utada's experimental side.

Although The Workout took some getting used to. I think the song seemed a bit "awkward" on first listen, but after that I loved it.

A song recently that's REALLY grown on me was "One Night Magic (feat. Yamada Masashi)". I never liked that until recently, despite loving every other track on Ultra Blue.
I was also never really a fan of "traveling". Until recently I never really listened to it, but now I love it.

Also included are:
Stay Gold
Arashi no Megami
