In this spot of Olay's 'Best Beautiful Stories' commercial, skin cancer survivor Hillary Fogelson shares her story, telling viewers that she was only 25 years old when she was first diagnosed with the disease and urging them to take care of their skin and see a dermatologist. As the commercial continues, Fogelson, a 38-year-old wife and mother, is being made up for a photoshoot -- and when she sees the results at the end she gets choked up, and there's no doubt you will too. Throughout the moving ad, a light, jingly tune plays in the background. What is it?

The song is 'Corner' by Allie Moss, a singer and songwriter who released the track in 2009, included in her second album, 'Late Bloomer.'

The tune was also used in a commercial for a UK internet service provider, and proved so popular that it reached No. 70 on the charts in the country. (It was also included in an episode of 'Pretty Little Liars.') Moss, who hails from New Jersey, is also a regular lead guitarist for Ingrid Michaelson, and has had other tunes featured in television shows like 'Parenthood' and 'Bones.'
