Need help extracting music from video file

I have a video file of a movie. I want to remove the songs to make my own soundtrack but there are voice layers on top of some of the music. Does anyone know how to separate the tracks so I only have the audio. I’ve used a few free programs but all I get is a two hour audio file of the entire movie. Thanks.

Is that not what you want?

I want the songs without the voices on top, is there any way to separate it? There is no official soundtrack to this movie and no songs posted anywhere.

Probably not.

What do you mean by voices?
Do you want to keep the dialog or the music?
The first needs Center Isolation and the second Center Removal.
Both won’t give great results.
Attach a audio extract if you want an example separation.

Thanks. I want to keep the music only
