A UNIQUE?

[Akutenshi]

So, I have friends who have expressed interest in Ayu, heard a good amount of songs here or there (based on me playing them ), and I'm trying to really increase their interest in her. So I wanna make a compilation of her most UNIQUE songs.

What I mean by unique is, songs that sound almost nothing like anything else in her discography (a tiny bit similarity is fine). I wanna know what people think are her most unique songs, so I can compile a tracklist from there.

14-16 tracks please.
