Semi,the most important thing that you are going to get out of this exercise is bigger ears because you're gonna be running your playback device into the ground!
Another way to figure out backing tracks is to isolate each track of similar styles in the mixer section of your keyboard and listen to it at least 10x.This will further give you an appreciation for how seemingly simple music can be sometimes when,in reality,it isn't.
