'Diamonds' by Australian singer Josef Salvat is the most popular song in an ad this week after featuring in Sony's 'Ice Bubbles' spot.
The understated version of Rihanna's original 2012 hit accompanies the brand's campaign for its new Ultra 4K television.
Taking the second place in our Shazam chart is Tom Odell with his cover of The Beatles' classic 'Real Love'.
The acoustic ballad is the soundtrack to this year's John Lewis campaign, which tells the story of a young boy and his Arctic friend Monty the penguin.
And Microsoft come in at number three this week with K-pop track 'I Am The Best' by Korean girl band 2NE1.
The upbeat number is the score to Microsoft's latest ad for the Surface Pro 3, billed by the computing giant as 'The tablet that can replace your laptop'.
The charts are based on the number of times each ad has been Shazamed over the past week using music identification app Shazam.
