This is an Okinawa song. ?(hana) means "Flower." The melody tune is very unique or different from J-pop. Because, I think, Okinawa has its unique culture for its own. It appears also in the Okinawa song. I respect its culture lasting for a long history.
"TOUCH" is my favorite song by Earth,Wind & Fire. Every summer I feel like listening to it. The changing patterns of the screen(my way) may not be very interesting again, but the song is wonderful!!
