What are the best ayu songs for these emotions?

[zellyx]

I think Ayu is one of the most emotional singers with powerful lyrics.

I'm curious to know what you all think is her best for the basic feelings..
best lyrics, melody, or really anything.

Sadness, Heartbreak, Anger, Happiness, Fear, etc.

Also, a really dear friend of mine is a huge ayu fan and is going through a rough time, feeling down lately. What are you favorite encouraging ayu songs?

Also, your favorite emotional performances?

I decided not to make this a poll... because how do you add every Ayu performance and song to a poll....
