Do you know the virtual singer, Hatsune Miku who was featured in Google Chrome's commercial in Japan?
The virtual singer is a software for making song on PC. If you want to get to know her more, just click here. I read an article related to her. I learned that she is very in-demand, in fact she is not just in the virtual world but you can find her in some products, now totaling 10 billion yen (about $82 million) in sales.
Users can make original song and then upload on the net such as in YouTube. It attracts a lot of people and increases the fun.
