The eighth score in the franchise, and this movie would bring a much needed breath of fresh air into the series. It is arguably the best in the entire franchise, but many would probably place it second behind The Wrath of Khan. This would see the return of Goldsmith once again, and he would never leave the franchise once he became involved this time (that is until his death).
The theme presented here is a bold, and somewhat nostalgic if I may say so myself. A heroic theme is what Goldsmith wrote here, and he would use it plenty of times through out the score. Also returning would be the Klingon theme and not much has changed with the theme other than the fact that the tempo had certainly been increased which made feel like a true battle theme. However it's probably best to call it the Worf theme by this time since he is the only Klingon appearing in the Next Generation movies from this point on.
The Blaster Beam would make a reappearance in this score. A mutation of his electronic "Blaster Beam" in a heavy, relentless minor key motif to portray the mechanized Borg. The Borg theme is used in different ways such as with the Blaster Beam, but also with heavy brass when the Borg Cube first appears.
A note should be taken that Joel Goldsmith also worked on this score because Jerry Goldsmith had run into scheduling conflicts and had difficulties completing The Ghost In The Darkness which is a fine score in itself.
