Vocaloid - voice synthesizer created by yamaha that has many different character voices.
Hatsune Miku is numeral uno when is comes to vocaloids. She has a voice range never achievable by any human. This pixel princess is huge in Japan, and has released many albums with her songs.
Her song are available on itunes. Just go to the itunes store and type Hatsune Miku into the search bar. They have hundreds of songs by her, and sung by her. There is plenty of variety.
I have bought some of these songs and they are wondeful. I redomend:
- World is Mine
- Far away
- Electric angel
- Sweetie Sweetie
- Po Pi Po Vegetable juice
