VOCALOID2
According to Akiba blog and several other sources seems that this music software has been really successful (it's on top spot of Amazon Japan sales ranking) and the first printing is already sold out. Vocaloid is a technology and application software developed by Yamaha that enables users to synthesize authentic-sounding singing by just typing in the melody and the lyrics of a song. Yamaha announced its development in 2003, and in 2004 the first application software product was launched. It was not released as a Yamaha product, but a software package of Vocaloid Singer Libraries developed by third party licensees (Zero-G and Crypton) which included Yamaha's Vocaloid software. Vocaloid 2 singer, just released by Crypton, features the voice of Atsune Miku: a 16 years old virtual Singer (according to her official bio she is 158 cm tall, weights 42 Kg and loves pop and dance music).
These are official MP3 demo songs: Song 1, Song 2 and Song 3 or YouTube medley.
