Go ahead, listen to it. It's absolutely beautiful. I'm going to see this one next week when it comes out here. The strange thing is I'm usually drawn to listening to movie/game soundtracks out of a feeling of nostalgia for the game or movie. That is to say that I want the music to color my life in the same way it does the film or game that they're from. I haven't seen this movie yet, but I still have a fond affinity for this score. When the composer was asked about the familiar feel of the music he replied:

Although the bulk of the score is all original work there are two "found objects" that inhabit a couple of cues. They are both piano pieces: the slow movement of Schubert D.959 and the well known "funeral march" from the Chopin Op.35. I used these fragments in the film after discussing with Ari his reasons for including the Schubert in the original trailer - turns out his mother was a pianist and that these pieces meant something to him personally. So it made perfect sense to refer to this material in a couple of scenes.

Anyway, read the interview with Max Richter on the Playlist.
