Yes, what you are looking at is illegally uploaded material. The full scores, aside from some cues from "The Best of Both Worlds", to every episode
Jones scored, was released as a multi-disc set from
Film Score Monthly (carried by Screenarchives.com now). I would suggest to anybody reading my post who has the money and loves his scored enough to buy the set, to get it; it's not sold very well.
My review of the set for anybody that needs help deciding:
http://maintitles.net/reviews/star-trek-the-next-generation-the-ron-jones-project/
For me, cue for cue, the best score is hands down with no competition, "The Best of Both Worlds".
Other strong scores just below that include:
"Who Watches the Watchers?"
"Booby Trap"
"The High Ground"
"A Matter of Perspective"
Worthy nominations include:
"Up the Long Ladder"
"The Defector"
"Brothers"
"Data's Day"
"The Devil's Due"
Special mention to a score so unremarkable and annoying there isn't -- in my opinion -- a single cue worth hearing, "The Royale".
