Probably first in the world history?
Oricon(Japanese Billboard)’s [J] CD album chart in 5th week of May 2010 reported that the week’s No.1 was “EXIT TUNES PRESENTS Vocalogenesis feat. Hatsune Miku” [J, Amazon Japan], which is a compilation album by Vocaloids, a series brand for several voice synthesis software packages based on Yamaha’s technology published by Crypton Future Media, Inc. [J] and others.
# No.3, 4 and 5 were Justin Bieber, Lady Gaga and Ke$ha by the way
It is reported [J] that the all artificial vocal album taking the No.1 is the first in history.
Songs and videos made with the Vocaloid software is one of the mainstream sector on Japanese user generated video, especially on a mega video sharing site NicoNico Douga. Most of those songs were written by amateur composer who play around there.
The number of the sold CD was 23,153 in a week. That is “lowest sales ever in Oricon chart history” analysed by a fan blog [J] of Hatsune Miku, the most popular Vocaloid character. There have been many Vocaloids’ compilation albums by the label [J], and one was sold more in one week, 56,000 copies but ranked at 4th at that time. So recent declining of Japanese CD sales may lower the bar. But anyway this is a historic achievement, and it was likely supported by web users.
Here is the promotion video of the album from NicoNico Douga,
