NEVER EVER, RED LINE and marionette are in 6/8 as well
JEWEL: it's purely 4/4
Humming 7/4: it's a mixture of 3/4, 4/4, 7/4 and even 2/4

on the other hand, has anyone done any statistics on key signatures?
interesting examples:

1. tritonal modulations (supposedly a rare thing in pop music):
You were: B major and F minor
Over: Bb minor and E minor
SEASONS: D minor and Ab major
Fly high: A major and Eb major
Boys and Girls: F major and B major

2. Free and Easy has the most key changes
intro: F# minor
1st verse: Eb minor
1st bridge: E minor, F minor
1st chorus: G# minor
transition: F# minor
2nd verse: Eb minor
2nd bridge: E minor, F minor
2nd chorus: G# minor
3rd bridge: E minor, F minor
3rd chorus: G# minor
4th chorus: A minor
ending: E minor

3. least used key signatures
G major: Greatful days, RED LINE
Bb major: untitled ~for her~, AUDIENCE (chorus)


And albums usually follow the basic plan of starting with minor key songs (2/3) and ending with major key songs (the remaining 1/3). Ayu's fundamental concept had always been a progression from darkness to light.
