[Delirium-Zer0]

But Humming 7/4 isn't IN 7/4. The intro and bridge are in 6/8, the chorus is in 2/8 and the rest is in 4/4. x_x

Though it IS strange that she uses multiple time signatures in one song (also done in HANABI ~episode II~ where she goes from 6/8 throughout the song to 4/4 in the instrumental section in the middle). So yeah, you can still love her for her unusual use of time changes.
