Who recorded the vocal track associated with McDonald’s “I’m Lovin’ It” campaign?

Justin Timberlake recorded the vocal track associated with McDonald’s “I’m Lovin’ It” campaign.

The campaign’s musical identity grew from a song and advertising concept developed for McDonald’s in the early 2000s. Timberlake’s vocals helped connect the commercial track with a major pop-culture name, while the short “ba da ba ba ba” phrase became the part most consistently heard in McDonald’s advertisements.

The campaign launched globally in 2003 and became one of the company’s most recognizable branding efforts. McDonald’s used the same core slogan across numerous countries, though advertising executions and translations varied by market.

This fact is sometimes confused with the identity of the advertising agency or songwriter involved in the campaign. Timberlake was the recording artist associated with the vocal performance, not the sole creator of the entire marketing campaign.
