There's lots of great songs by Flower! I only know a few, but they're sooo good! Here's my personal favorites!
Closer to You!
(I'm sure a lot of you know this one already)
My second favorite song by Flower. The first time I heard it, i had assumed the song was brand new and made for Flower. I had no idea it was originally arranged for another vocaloid. It just flows that naturally!
A classic, THE classic. This is easily is in my top 5 Vocaloid songs ever. I love it so much!!
