i've been searching for a long time to this soundtrack collection, yet the classical music mp3 that brought by say, Beethoven, Chopin, Tchaikovsky, Gershwin, etc.
I found a complete soundtrack in a zip file , exclude the classic music that featured in the film.
you can download this ZIP file at H E R E .
you can also download the classic songs at CLASSICCAT , A-M CLASSICAL , or at CLASSICONLINE . You can also just googling the best source that fit you, if you like.
After all , enjoy the music !
