Which singer performed the early McDonald’s “I’m Lovin’ It” campaign song released in 2003?

Justin Timberlake performed the early McDonald’s “I’m Lovin’ It” campaign song released in 2003.

Timberlake’s recording was connected to the launch of McDonald’s global “I’m lovin’ it” branding campaign. He also appeared in a music video for the song, helping associate the new advertising identity with a major contemporary pop performer.

The campaign’s musical origins involve several contributors, which causes a common mix-up. Pharrell Williams was involved in the song’s writing and production, but Timberlake is the singer most directly identified with the released vocal performance.

The advertising phrase and its short musical hook ultimately became more famous as a McDonald’s brand asset than as a standalone pop release. The campaign continued internationally after its 2003 introduction.
