Who performed the vocal track used in McDonald’s “I’m Lovin’ It” campaign?

Justin Timberlake performed the vocal track used in McDonald’s “I’m Lovin’ It” campaign.

The campaign launched in 2003 and connected McDonald’s branding with a pop-oriented musical identity. Timberlake recorded the vocal version associated with the advertising campaign, while the signature “ba da ba ba ba” hook became the most recognizable audio element. The campaign’s music helped make the slogan memorable across television and radio advertising.

A frequent misunderstanding is that Timberlake wrote or solely created the entire campaign. The brand platform involved advertising agencies, composers, producers, and McDonald’s marketing teams. Timberlake’s role was as the featured performer on the vocal track. The campaign also became notable because it used one consistent slogan and musical motif across many countries, helping McDonald’s present a more unified international identity.
