I like to think of a song as a pencil drawing. It is the most important part of the drawing, because it defines what it is you are looking at. But with good musicianship and the production, the colors and the frame, it can be made to resemble many different things. You could draw a picture of a cowboy, but then you could color it in with strange colors and make it a psychedelic cowboy. Or you could color it is with traditional instruments, make it rustic and dust worn, and it could be a traditional country western song. You could put it up with no frame or you could put a frame up around it that makes it look as if it should hang in some expensive gallery. That’s what musicianship and production do, they take that thing that is either great or not on it’s own, and make it presentable to more people. A great song, like John Lennon’s Imagine, would be great in any form, whether just as a sketch or as the final product, produced by Phil Spector. Meanwhile, you take something like Daft Punk’s Random Access Memories, and although there is some song craft going on there, most of the true magic is in the production and the musicianship. They are taking a simple drawing and making it into a piece of art through attention to detail. Meanwhile I just looked at the Billboard Top 20. Most of that stuff is like someone pissing on a canvas, putting it in an expensive frame, and then telling you it is is a portrait of Jesus.
