I really doubt they will use ayu's song..in the past there is only one song that actually featured a song by ayu..
the Bake CM that is...

Well, BAKE is pretty much the only product that doesn't already have its own little themesong :\

Hi-Chew had its 'kuchara happi happi~!'

And yeaaaaaaah~:D Go About You/is this LOVE? :DDD

Is This Love's one was so classy. And elegant.

Maybe it'll just be a CM featuring Rainy Day or Ladies Night to promote sales for Miss understood. Possibly even Teens.. *shudders*

Seems like she gotta feat. a handsome male artist in the cm. The hero of SHINOBI maybe...

speaking of hi-chew....none of the hi-chew CMs have her singing....i wonder why...

hope that a preview from her new single will be out then :D
looking forward to it :yes

Since Morinaga CMs have been using rock songs, and if GRAVITY is suppose to be a rock song (sounds like one)...Could it be???

^ perhaps. i agree to a certain extent. but who noes GRAVITY may be a ballad lol.
