Finally! You guys in Japan have been able to hear the "My Story" ringtone for weeks now, but this is the first audible glimpse the rest of us have had of the song.
It hasn't hit the YouTubes yet (see below update), but the official Kanebo/Lavshuca web site has both versions of the commercial (click the "With PUFFY" nav button). It's kind of interesting - one has Ami singing softly over the song, the other Yumi. Makes it a little hard to hear the song itself, but it's always kinda cool to hear their individual voices untouched by studio effects.
What I can hear of the song actually sounds pretty good!
UPDATE: Here they are, straight from the Tube of You.
