マトリョシカ (Matryoshka)

Background
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 would take from a few months to a year to achieve). It is one of the most popular Vocaloid songs ever released.

The 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 had been interpreted in various ways.

Piano sheet music appeared in the ピアノソロ やさしくひける ボーカロイド Selection for Piano 2 collection. This song has also appeared as sheet music in the Vocaloid Best selection series, as well as in the Vocaloid Superselection piano solo collection. This song also featured in the mook ボカロ☆バンドスコア.

This song is featured in the EXIT TUNES compilation album Vocalonexus.
