Hi, which Ayu song(s) best reflects her singing ability in your opinion?

I'm watching her Pride FNS Performance currently and i'm getting all the goosebumps! In my opinion, I think Pride is a very good song that reflects Ayu's singing ability. I find she controls very well, in terms of the whole song's climax and especially, her techniques.

What do u guys think? Any ultimate song which you feel that Ayu is able to show her powerful singing ability?
