Ievan Polkka (Eva's Polka) is a song written in the 1930's, set to a traditional Finnish melody. After falling from popularity it was revived by Finnish band Loituma in the 1990's, and in 2007 a cover by Otomania was released, voiced by Hatsune Miku and accompanied by a video illustrated by Tamago. The song is featured on the albums Hatsune Miku 1st Song Album, VOCALOID2 MAXI Single Vol. 1 ～みっくみくCDにしてやんよ～, 初耳, and 初音ミク-Project DIVA-F Complete Collection.
