This there is tough competition, mostly from Hans Zimmer who have done breathtakingly beautifule score for 'Inception'
I loved 'social network' package..by package , i meant everything, performance, direction, music ..every single thing in this movie is simply awesome:) Remember those boat race sequence which got amazing background score.. A Well deserved Award :)
