Actually I enjoyed more Tiberian Sun + Firestorm, than Red Alert 2 and Yuri's Revenge. Firestorm's soundtrack differs much from the original Tiberian Sun, because it's better. It is less atmospheric and more lively, like Tiberian Dawn and Red Alert one. Also it got more synthesizers and acid sounds. Of course the original has its nice moments like Approach, Pharotek, Lone Trooper, Scouting and Valves. Frank is a genius.
