When it comes to music in commercial/advertising films, instrumental music or sound design often works more effectively than vocal songs. As a composer and music licensor, I lean towards using music without vocals and lyrics as it is more efficient in conveying the intended message.
In the case of using songs, they would work well (sometimes perfectly) if they were written for their specific concepts. But it’s often difficult for agents and music supervisors to complete the job within a short turnaround, by spotting suitable musicians and making sure they complete high-quality songs along with appropriate lyrics.
A long ago, in the early TV era, there used to be many commercial songs where product/company names were repeatedly sung, but we who live in a modern age would be embarrassed if we encounter with such trite approaches.
Placing existing songs also sometimes works well, but it could cut two ways. While lyrics of the song could enhance or expand its world and story, they could bring some information redundancy and take attentions away from what they want to convey. Even worse, it just could end up with promoting the emerging band’s song or resurrecting the old hit song. Using songs on commercials tends to involve many “temptations,” which could be pitfalls from the perspective of their true goals.
Speaking of engaging the audience, the use of sound design and instrumental music can be a powerful tool. While it’s still a challenge to place/compose music that works effectively, some outstanding commercial works demonstrate that it’s possible to enhance audience focus.
Today’s choice is “Nike Pro Combat” (sound design by Machine Head). This commercial film resonates with me because it is tightly focused and tied in terms of the relationship between its sound, motion, and message. While there’s no voice-over narration on the movie, obviously you could catch what they want to convey through this.
Imagine when you hear anthemic rock songs or epic orchestral music played in this movie. It might work and be even “entertaining,” but obviously it ought to lose this tightness and tension. This is solid.
