I heard it in the summer and around the beginning of this year.

It's a pretty song that has a music box feel to it and has a woman singing it in what you can call a lullaby. Has a soft electronic and ambient musical background. You can't make out what she's singing and you can't tell if she's singing in English or in another language like french or German. It's a really pretty song that makes you feel in a magical trance.

I really can't get it out of my head. Please help
