Ayu's biggest hits?

[Tom Punks]

I would like to know which songs are considered some of Ayu's biggest hits (in Japan, not at AHS). Like the songs that more Japanese people would be able to identify?

I have an idea of which ones are, but I'm not completely sure. Like I remember reading once someone saying Startin' got a lot of radio play, but I don't really know if it was a "hit" or not.

Thank you.
