I do home there's more to it. I think the most significant element missing is the "conversational" element to it, where different parts of the arrangement "talk" to each other. It's the key component of any great piece of music from LVB to taytay.
I think rock music is the best indicator of this, since all the "sections" are reduced down to individual parts. All even do Digits a solid and toss out Rush as the best example
You've got three guys who are each a virtuoso at his instrument, and so each song is perfectly divided between them. Yet they are all almost always "saying" something different. Sometimes each might be saying his own thing, sometimes Alex and Ged are talking to Neal, or any of the different possible combinations. The only time they speak in unison is when they want to create emphasis or exclamation. "YYZ" is the perfect example of this.
A really good Trek example of this is the TUC overture.
Eidelman starts out with the strings and baritone horns making an ominous predication. Then the woods timidly speak up against it. Then the chorus and percussion come in and talk over both trying to quell the disagreement before it becomes and argument - but there's that moment it realizes it has failed, creating a moment of tension before it all erupts into each section shouting at one another.
But the DSC theme is just every section saying the same thing in happy agreement. You see, great music requires conflict too.
