I have seen huge amounts of traffic and emails to me based around Apple advert music, so I thought I’d better nip this one in the bud.
The author is Yael Naim, a pretty extraordinary singer, in multiple languages. Following is the youtube video I found while searching it for myself. I need to go out more.

The song is ‘New Soul’, and I’d recommend you check out others of her English-based songs from the album (other languages are cool, but the English ones flow better to me).
Here’s the iTunes store URL.
