Audiosurf: Unionest.NET - 花詠束 (HD) (part1)
Its actually:
花詠束 -All our happiness is plucked from the thoughts of each and every one of you
but the title was just too long
So I don't need to play as the mariomarathon is just running right now.
This track's another interesting variation of medley.
Instead of stucking together lots of music, its using only one track and using lots of different styles.
But this makes the track a lot more difficult than it sounds.
