Zutto...: It is a nice winter song, I like it but definitely not her best winter song nor the best song on the single. Her voice sounds too "pitchy" sometimes, but is tolerable. I'm sure it will grow on me, The more I listen to it the more I love it.
Last Minute: I love how Ayu sings this song *___* So emotional and powerful. Some people say something about bad mixing but honestly I can't hear it .__.
Walk: for me, the best song on the single and maybe the best one this year. I love everything about this one, so nostalgic and Ayu-ish. It sounds sad and at the same time gives a hint of hope. Not to mention how beautiful and meaningful the lyrics are for me. Komuro's compositions for Ayu never disappoints me
And I can truly feel Ayu on this single, as some people said this feel like a "come back" of the original Ayu
