Unfortunately, the guy they got to score TNG couldn't come up with anything much more memorable than "library music" is. In fact, I'd say some of the library music I've heard is better than what they used for TNG, and most of the new series in general. (With the exception of the main themes.)
There were ultimately a handful of composers on TNG and the subsequent spinoffs, including Dennis McCarthy, Ron Jones, and Jay Chataway. But from what I remember reading when the shows were first run, the mandate for the generic, non-thematic score music came from Rick Berman. Apparently he didn't want the music to upstage the acting or something like that. That's why Ron Jones (who scored "The Best of Both Worlds") ultimately wasn't invited back, he kept trying to put themes into the scores. Dennis McCarthy and the others stuck to the, as you call it, "library music" routine. I don't argue that the boss can't call the shots, but I don't have to agree with it. I wished the music in TNG and the shows that followed followed in the musical manner that we fell in love with on TOS.
