Which singer provided the lead vocals associated with McDonald’s 2003 “I’m lovin’ it” campaign song?

Justin Timberlake provided the lead vocals associated with McDonald’s 2003 “I’m lovin’ it” campaign song.

The campaign was developed as a global branding platform and used a short musical hook that became closely tied to McDonald’s advertising. Timberlake recorded the vocals for the song, while the production involved the Neptunes, the production team associated with Pharrell Williams and Chad Hugo.

A common mix-up is to credit Pharrell Williams as the singer because he was involved in writing and production. The campaign’s musical origins also involved the German group Jung von Matt and the recording artist Thomas Bangalter’s broader creative circle, but Timberlake is the performer most directly associated with the English vocal recording.

The phrase became a long-running McDonald’s brand signature and was adapted for advertising in many countries and languages.
