Which of Ayu's Songs has the most lyrical meaning?

[ZeroS]

I love Naturally so much... When I listen to the lyrics I always get the feeling, that the song is written for me

Wow..i never knew Ayu had THIS deep meanings...i could only feel from the surface of them (esp. STEP you)

i could only feel the ones which were easy to understand yet very sentimental like MA and Moments..

hopefully more people can contribute..very interesting to read..hehe

I need to think about this more, but for now, I am thinking of HAPPY ENDING. I could totally have fun analyzing the lyrics and bringing in connotations related to "Happy ending". (I study English and art, so analyzing is kind of what I do )

But really, there are so many songs I wouldn't know what to choose if I had that assignment!
