Here's an really interesting english article about her career, take a look (it's a bit old, but nice to get into her):

She's so impressive!
And now doing this agriculture project... she's truly a great rolemodel for everybody.
But I do think music was just a step for her career, she tried to get publicity and arouse public interest. Music never was her life.
I don't think she will do music in the future.
