RAINBOW is my first Ayu album so it'll always be a fave in my heart <3
The older I get I can see how this album isn't as cohesive as others. I feel like if RAINBOW came out in the modern era it would be a two-parter: RAIN and BOW......lol
RAIN might have collected the more etheral and dreamy tracks like everlasting dream, everywhere nowhere, Over, but finish on Free & Easy and then BOW might have had the "harder" track
s 
like WE WISH, and some more upbeat and lively-sounding tracks like independent, Real Me and finish with July 1st.
Then she'd release RAINBOW and we'd all rage at it.....
