Aha, but as Picasso said, you must know the rules before you can break them. It does help to have a bit of grounding in theory, so that you're not just randomly stabbing components into things and hoping it works.
I get really, really annoyed and frustrated when I read posts by people saying stupid shit like "I wired an LED in series because I wanted it to light up and now it doesn't work but it should work and it doesn't because it's an LED and theory is hard and Reed Ghazala says you don't need theory. How do I make it work?"
Well, read a bloody book on simple electronics, then! Jeez, it's not hard. At least learn some of the terminology, what it means, and how to apply it. The only way to learn how to do things is to actually *do* them - try stuff, and learn from what doesn't work. *But* - you need to know what's *likely* to work, and for that you're going to want a bit of theory.
We know intuitively that some combinations of food work well. Putting salt on strawberries? No, you put sugar on strawberries! How do we know that? Well, it's not innate - we learn that sweet things work well with sweet things, mostly. Occasionally something comes from way off out the side, like strawberry jam and cheese on a sandwich (it works well, try it with a particularly strong Cheddar) and you think "how the hell does that work?" But then you discover that it's not about the sugar and the salt, the fats involved come into play as well. It's definitely not as good with marge or low-fat spread than it is with butter - you've got to get the fats right.
Electronics is the same - you learn how to build things up intuitively, just as with music, and just as with food. The theory gives you a clue for where to start.
