Speculation is the group KAT-TUN will sing the Movie 9 theme song. I think ive only heard one song by them. Will be interesting to see if this is the case. I really liked Chiisaki mono and Hajimari no Uta. Hopefully if KAT-TUN is the group that sings the theme, it will be in the league of the aforementioned songs and not lovely boy. A CD soundtrack announcement for m9 should be in late may/early june.
