McDonald's: The Golden Number by NORD DDB

Back in the mid-noughties McDonald’s rolled out the ‘I’m Lovin’ It’ jingle fronted by American singer Justin Timberlake, which has since become synonymous with the brand.

While many people recognize the catchy song, they may not realize that you can recreate it using the keypad on your mobile phone. McDonald’s Sweden, alongside agency partner Nord DDB, is tapping into this with a unique campaign called ‘The Golden Number’ that asks fast-food lovers to play the tune with the keypad of their phone and call that number.

Finding the right combination of numbers is the tricky part, but once the correct sequence is found entrants need to phone it to be in with the chance of winning a gift card that can be used at any golden arches location in the country.
