Other albums, such as 19's Sound Factory's "First Sound Story" and Livetune's" Re:package", and "Re:Mikus" also feature Miku's voice.

Another song original sung by Miku, "Color", was covered by Maria, and featured as the opening theme of the 2011 anime series "Freezing".
Miki Furukawa
In 2006 Furukawa released her first solo album, "Mirrors", featuring a mixture of guitar-based rock songs and electronic dance-pop. "Bondage Heart" (2008) pointed in a new direction, with heavy influences from post-punk, psychedelic rock and noise, whereas "Very" (2010) was a mostly electropop-oriented record. In December 2009, software developer AH Software used voice samples from Furukawa to create the Vocaloid voice library SF-A2 Miki. In 2011, Miki Furukawa and former Supercar bandmate Nakamura Koji formed the band called Lama. Lama jump-started their formation with a single entitled "Spell", which has been used as an opening theme for the anime "No. 6". The single "Fantasy" was used as the ending theme for the anime "Un-Go".
