A number of questions are being asked here. I’m going to limit myself to answering two. What makes someone use a new, undiscovered song?

While it can encourage unknown songwriters to have churches singing their songs, there’s no reason to use a song simply because no one else has heard it. The church doesn’t have any inherent responsibility to support struggling songwriters. The fact is, a lot of songs are unknown because they just aren’t that good.

The way for an unknown songwriter to get others to sing their songs is to write increasingly better songs. Songs that really serve the church. Songs that are easy to sing and remember. Songs that are filled with life changing biblical truth.

When we as worship leaders choose songs based on whether or not they’re well known, we’re allowing an unknown majority to determine what we sing, rather than prayerfully considering what will best serve our congregation.

There are a lot of things to consider when choosing a song to teach my church. They include biblical faithfulness, lyrical and musical freshness, the history and experiences of my congregation, and musical accessibility. But as far as I know, “hit status” isn’t a requirement. There are songs that are widely sung that, for different reasons, I wouldn’t use on a Sunday morning.  

On the other hand, I may choose to use a song that’s not the “best” song because someone on the team or in the church wrote it, and it really serves the particular season we’re in. We’ve found that people are often more receptive to a song when they know the person who wrote it.

But everyone will be served that Jesus will be glorified if unknown songwriters continue to improve the quality of their songs, and worship leaders increasingly choose songs for the right reasons. - Bob Kauflin
