Which Ayu Song are you Currently Obsessed with?

[chibi_sunny]

I always listen to Ayu's songs, whether they are old or new, and each time, I get hooked on a song. I guess going back and listening to her older songs makes me realize how good she is and how each song is different.
Right now, i really love Heaven, which in my opinion is one of her best ballads...i also think that Voyage is awesome, especially with the different background vocals; it sounds heavenly. Before, i wasn't very crazy about Voyage.
So, i wanna know what songs by Ayu you guys are currently interested in, and why do you feel that way?
