I ran across this post (link) which provides a useful pair of videos. If you are not already sick to death of Bentley's demonic anti-Christian "revival," you may want to watch the first clip in its entirety (especially the reminder at the end). Otherwise, for the point I am making, you need only to watch the first minute or so of each. The post is provided by the blog titled (in this case somewhat unexpectedly) Let My People Read, by someone who is more charismatic (in both senses) than I am.
Now, for the comparison, watch the video embedded in this post (link).
One form of worship shows us the imitation of the world: the other shows the transformation of the world. One video shows man-made worship: the other inspired worship. One is the logical conclusion of strange-fire innovations in worship: the other a restoration of Orthopraxy.
Thankfully most folks who reject the Regulative Principle of Worship (or who consider the lyrics of praise merely an element) do not take it to this absurd logical conclusion.
P.S. It's worth noting that the Psalms are still sung in "Orthodox" churches, normally (if not always) as the Apostles would have done in the synagogues, a capella. There have been some innovative additions in the song of EO worship as well (various Troparia, for example), but less addition is found there (in that regard) than one finds in a typical church that has innovated more freely. A post today by the Romanian Orthodox poster, Lvka provides some examples: (link - there may be some objectionable icons in some of the still images that accompany the audio in the clips Lvka has embedded).
