Made in celebration of Miku's birthday, this is a rather chaotic and addictive alternative rock composition which reached over a million hits with incredible speed (less than 32 days, a feat that most other well-known songs take from a few months to a year to achieve). It is one of the most popular VOCALOID songs ever released. Most of the lyrics are nonsensically vague or ridiculous, with a slight hint of pain or sadness, giving the overall song a crazy and psychotic feeling. Because of this, the lyrics have been interpreted in various ways.
