Which musician recorded the vocal for McDonald’s “I’m Lovin’ It” campaign song?

Justin Timberlake recorded the vocal for McDonald’s “I’m Lovin’ It” campaign song. The campaign launched internationally in 2003 and used the phrase as a broad, adaptable expression of enjoyment connected with the McDonald’s brand.

The campaign’s music developed from a track associated with the German creative scene and was adapted for McDonald’s global advertising. Timberlake’s vocal performance helped turn the song and phrase into a recognizable audio identity, while producer and songwriter contributions shaped the commercial recording.

The campaign title is sometimes mistaken for the name of a standalone pop single. In McDonald’s branding history, “I’m Lovin’ It” is principally the company’s global advertising platform and slogan, supported by music, television commercials, packaging, and localized marketing.
