Some people don't like how a lot of modern worship songs are repetitive.
"Each of the four living creatures had six wings and was covered with eyes all around, even under his wings. Day and night they never stop saying:
Holy, Holy, holy is the Lord God Almighty who was, and is, and is to come."
That, along with Rev 4:11, gives us a pretty clear example of repetitive worship - for eternity. Of course, rich imagery is also another great aspect of worship, and you see that throughout the Psalms, Hannah's prayer in Samuel, and many other places. There's times for both. But neither should be disregarded as worship, and both can be embraced as a means of praising God.
After all, any truth about God is worth saying more than once!
