@Finn dAbuzz,
It's probably no shock to a lot of people here at a2k but I truly love and obsess over movie scores.
On Amazon alone, I own the scores for:
Coraline; Drive; Inception; Lord of the Rings; (YES! High five anyone?) Princess Mononoke; and Waltz with Bashir.
I also own Schindler's List on CD which was my first film score I owned.
One day soon, I'll own a copy of Trevor Jone's score of Michael Mann's The Last of the Mohicans. Also, Ennio Morricone's The Good, The Bad, and The Ugly.
I love original scores that are epic and ambitious. But I also like the oddball modern score of The Social Network as well which I also own a copy of somewhere.
