I don't know all of them, but I believe the most recent one is 'Too Close' by Alex Clare. There was also one that had 'When I'm Gone' by Wiz Khalifa.
Pat attention to the commercials more when watching themm; other than that you could shazam it..
I've only ever seen the one Bing commercial with the song Too Close by Alex Clare..
Wish I could tell you, Anna. But I hardly ever watch tv ;)
