Yes, cutting the visuals to suit the music is something a lot of shows do, but usually, the music isn't necessarily relevant to the visuals: it does what it's doing, the pictures do what they're doing. Sometimes, as with B5 season openers, the music is tailored to the action, but whatever it says about the show you're about to see is stated in fairly general terms--"lots of action, lots of passion, big explosions, you'll love it" kind of thing. With Space Rangers, the music said something very specific about this particular character. Imagine a B5 season opener, say third season, if instead of coming at the beginning of the long climb to the climax, Bruce Boxleitner's image had been saved for the moment when the music crested, and had been shown in a markedly different way from the others. (I'm not saying that would have been a good thing for B5, just that it would have had a very different effect on the way we viewed that character.)

I may be making too much of what may merely be a coincidental juxtaposition, but it seems too right to be merely accidental. The power of music is almost always underrated in film and telly.
