Ayu has said she's influenced by some classic rock bands. Which songs do you think reflect that the most? I say until that Day... and 1 LOVE, for sure.
I'm also going to add decision, kiss o' kill (listen closely!), End of the World, girlish, Who... (Across the Universe), identity, Are You Wake Up?, and Marionette to my personal list here.

Seems like a lot, but lately I've been noticing little details I hadn't noticed before. But maybe it's just me.
That version of Who... just oozes with it IMO...I can't believe I didn't notice it...
