Golden Globe Winner Predictions: Best Original Score

The competition: Clint Eastwood (Changeling), Alexandre Desplat (The Curious Case of Benjamin), James Newton Howard (Defiance), Hans Zimmer (Frost/Nixon), and A.R. Rahman (Slumdog Millionaire).
For your information: Desplat won before for “The Painted Veil” and Zimmer won for “The Lion King” and “Gladiator.” Eastwood has two previous nominations in this category and Howard has one.
Who should win: Probably Rahman
Who will win: Throwing Rahman into the mix shakes things up, but I think the score by Howard from Defiance will take the gold.
