Software creates songs, vocals from text

Frankie says:

Vocaloid is a software developed by Yamaha that enables users to synthesize authentic-sounding singing by just typing in lyrics and melody.

In the last two weeks Vocaloid 2 Atsune Miku stormed the Japanese otaku and video gamers undeground and many users posted their own music mashups created with Vocaloid 2 on Nico Nico (Japanese equivalent of YouTube).

Nico Nico promotion made this software an unprecedented sales hit among Japanese application software sales (it's on top spot of Amazon Japan sales ranking too).
It's really impressive how powerful this $100 software is!
