I am talking about using Audition

in the editing view. Listen to the music from beginning to end, find a section without background music (you can find it with most music), press the left button to select it (pull it white, pay attention to the accurate position of both ends). Right click - copy as new.

Insert an empty track in the multi-track view, right-click---Loop Properties--Enable Loop--OK, press the left button and pull it from the right edge to the required length, so that the drum beat track of the music is Separated separately.

This simple operation should be possible with audio editing software.
