[Vocaloid] My head's spinning with worries. Is there a gymnastics for that?

Head Gymnastics At first listen, it might sound peaceful and calm, but it's anything but. Miku's "gymnastics" is actually an intense headbanging session to "shake off all your worries"... Let's blast away all the negative thoughts to the powerful beat. "Shake your head when you wake up in the morning, keep shaking it till night, if you empty your mind like this, head gymnastics are so much fun!" "Shake your head to a fast song, shake it twice as hard to a slow song, if you empty your mind like this, you'll feel so happy!" - Song Lyrics
