Her Morning Elegance / Oren Lavie

How do you remove music from a movie clip and keep the voices on Audacity?
I have a handful of movie clips for my English project. The only downside is that they come with music that is different from the music I'm using. My question is, how do you remove or mute music from a movie clip, that's been converted to a audio file, and still have the music? Is that even possible?

Please be as detailed as possible.
