Right now Moan Soundtrack
I have to say that the Tron soundtrack by Daft Punk is AMAZING!!!
The Lord Of The Rings and Hobbit soundtrack/score by Howard Shore are also great.
Pulp Fiction! Tarantino puts together the best soundtracks in general, in my opinion.
Tarantino's soundtracks are usually really great! I especially liked soundtrack of Reservoir Dogs
Yes! Not only a great director, but an excellent soundtrack curator.
I really love a ton of what Thomas Newman does. The soundtrack for American Beauty is especially good.
