M, really a nice song for newbie Ayu-lover, at least this is the first song attracted me

So I think it worth overrating
Overrated: evolution, Boys & Girls, Trauma, walking proud, CAROLS, About You, and flower garden
Underrated: definitely For My Dear... at the first place

gave almost ignored
TO BE, monochrome, too late, End roll, vogue, ever free, Far away, Key, P.S II, NEVER EVER, HOPE or PAIN, Replace and many many nice songs are often underrated
