Thank you @theregularguy!
I love that song and her voice, too. She was one of these commercially hiped German pop idols some years ago. She was successful during a certain time but then things got worse. So she decided to go her own way, work autonomously and do music that really came from her heart. The above mentioned song is from her latest album. In my opinion she did absolutely right. Compared to her first steps into the music business, what she is doing now is really great stuff that goes deep and has a message. I like this story because it shows that we have to find our own way in life to become really fulfilled.
