rainy day was one of the songs that GEO composed for (miss)understood.
GEO did the following:
Bold&Delicious
Pride
Ladies Night
Beautiful Day
rainy day
In the Corner
All except In the Corner were included on SWEETBOX's Addicted album [In the Corner was on their other album, Raw Treasures].
Some had redone names, like rainy day = Every Step, and Beautiful Day = Beautiful Girl..
The songs though were given to Ayu by GEO, and it wasn't like she 'omg stole!' them.
