Ok, so first the easy part. What you don't have to do. You don't have to listen to the whole song, you can just begin at about 6:20 or 6:25 or so.
What you do need to do is turn that shit up, and specifically, turn that bass on you sound system.
They better the sound system the better the listen. Get in your car and bump it if you must. I recommend mulitple listens and listen for each and every instrument contributing.
Now turn that shit it up and the bass up even more and take your time with the piece of work...
