Some good soundtracks here, I like Top Gun, Highlander and Rocky IV - all great.
However, in my opinion, the greatest soundtrack ever is Last of the Mohicans. The others have good "songs" in them, but the combination of the soundtrack and cinematography by Michael Mann in LOTM is superb and it this synergy which makes the difference between a good film with some soft rock playing over it. The final "Promontory" scene is one of the best ever.
