The Christian worship charts are dominated by relatively few artists. Why might this be the case?

“If a song is going up the charts, there’s pressure on the worship leader to play that song,” said John J. Thompson, who worked with Christian artists as creative director for Capitol CMG Publishing and now runs the website truetunes.com.

Because songs must be catchy, they focus on simplified melodic structures, fewer words, and limited emotional range, with the goal that the congregation can catch on to new songs by the second verse, said Thompson, now the associate dean of the Trevecca School of Music and Worship Arts and the author of Jesus, Bread, and Chocolate; Crafting a Hand Made Faith in a Mass Market World…

Most of the songs on the list were written by Caucasians. Thematically, the songs tend to stay in the realm of praise and adoration without venturing too far into more complex themes like confession, doubt, and suffering.

Sandra Van Opstal, pastor, liturgist, and author of The Next Worship: Glorifying God in a Diverse World previously told CT, “…The worship industrial complex has become so influential that millions of people around the world are being discipled via iTunes. The narrative of God and faith is in the hands of a few worship movements who aren’t talking about how their social location, cultural values, and racial privilege shape their faith.”

In many culture industries, it can be difficult to predict what will become hits. There are hundreds, likely thousands, of worship tracks produced each year. There are ways that all industries try to hedge their bets. One route is to promote and support stars. In the list provided of popular songs, this means Chris Tomlin or Hillsong are better bets for hits compared to lesser-known artists. Another route is to try to cross-promote across platforms. Radio, even as a dying medium, can help drive traffic to streaming music and use of music in churches. Performing the songs in church can help drive congregants to the music and radio.

But, there are more factors at play. How does an artist become popular in the first place? At one point, Chris Tomlin was an unknown and the Hillsong movement had a limited reach. Stars can put out average or bad music. New artists can arise. The cross-promotion can fail to produce. Tastes and trends in music can change. Technology can change in both how music is made and delivered, boosting some and hurting others. How congregations view and utilize worship music could change. And so on.

More broadly, how culture and cultural objects come about is a complex process involving multiple social forces and institutions. In other words, this is not necessarily the way the Christian worship industry works at the moment or into the future. It is hard to know what kind of worship music will dominate ten or fifty years from now. Certain artists may be the music du jour today and be gone tomorrow.
