The song from the McDonald's advert is "I'm Lovin' It", performed by Justin Timberlake. It was originally written as a jingle for McDonald's and released as a single in 2003. The track has since become one of the most recognised advertising slogans in fast food history.
Justin Timberlake is the singer. According to BBC Newsbeat, "I'm Lovin' It is sung by Justin Timberlake and produced by The Neptunes, Pharrell's production duo with Chad Hugo." So when you hear that familiar hook, it is Timberlake's voice you are hearing.
The Neptunes, the production partnership between Pharrell Williams and Chad Hugo, shaped the track's sound. Their fingerprints are all over the upbeat, percussive feel that made it stick so effectively in the memory.
This is where the story gets more interesting. Timberlake performed the song, and The Neptunes produced it, but the jingle itself was written by rapper Pusha T. The New York Times reported this, and BBC News picked it up. For years, Pusha T's role in creating one of the world's most-played advertising hooks went largely unacknowledged in popular coverage of the campaign.
So the short version: Pusha T wrote it, The Neptunes produced it, Timberlake sang it.
The single was released in 2003, tied directly to McDonald's global "I'm Lovin' It" campaign. It was written specifically as a jingle for the brand rather than as a standalone pop record that McDonald's later licensed. That origin makes it unusual: most major advertising songs are adapted from existing tracks, but this one was built for the campaign from the start.
McDonald's rolled the slogan out across more than 100 countries, and the "ba da ba ba baa" melody became shorthand for the brand worldwide. As of 2026, it remains McDonald's active global slogan, over two decades after its debut.
Yes. "I'm Lovin' It" by Justin Timberlake is available on Spotify, Apple Music and other major streaming platforms. Search for the track under Timberlake's name and you will find it. It appeared as a single rather than as part of one of his studio albums, so look in his singles catalogue if it does not surface immediately in a standard search.
Repetition is the obvious answer. McDonald's has used the jingle consistently since 2003, making it one of the longest-running fast food advertising campaigns anywhere. The Neptunes' production style, built around tight rhythms and minimal arrangement, also makes the hook easy to recall after a single hearing. Pusha T's writing kept the lyric simple enough to translate across languages and cultures, which explains why a jingle written over twenty years ago still runs in UK adverts today.
