I mentioned to my pastor once about the repetitive nature of the modern songs. He agreed that it was repetitive. And that there was a reason. “You know how growing up you did the repetitive, rote responses between the preacher and the congregation? Well, we don't have that anymore.”
It is in the song. I can't remember precisely why he said that repetition is important. But he said what he does (and what I now do make the songs bearable) is to focus on God. Every time the verse repeats about how God is good, full of grace or whatever, focus on an individual way that God is “good” (or whatever) each time that word is sung. I've found that very helpful and worthwhile.
I find that repetitive *worship* music seems to be more designed to evoke emotionalism than true worship
One song leader said we only repeat it 8 times. He knew some that repeat it 12 times.
