I'm a fan of film scores, so this has been getting on my nerves lately.

Some soundtracks that are available for purchase are sometimes missing half the music that's actually in the film (such as Rango).

I was wondering if there is a way to get my hands on these missing soundtracks via ripping them from the film or otherwise.

Bonus points if you can get it done for me because my audio programs on my computer are shit.
Thanks!
