PLEASE HELP 
I want to separate back ground music (it’s a song) and dialogue of a daily soap. Is it possible 
Basically I need the back ground song. I have no clue 
PLZ HELP. I am not a expert on editing musics so if any chances please explain the detail steps.
Sometimes if it’s in stereo, you can get Effect > Vocal Remover to work.

Here’s a much more complete discussion. As above, if the work is in mono or is a bad MP3 download, it’s pretty hopeless.
