Having been into metal for barely three years, I;m nowhere near a point where I could say the "magic" has faded by any degree. There are quite a few genres I'm either not into yet or I've barely scratched the surface of, so there's tons of material, classics upon classics among them, that are waiting to be discovered by me.
I suppose that's one advantage to being a late-comer to metal. Not only do you have the current releases to get excited over, you have thousands of albums covering over 25 years to fall back upon whenever the current output isn't enough, which at my rate requires me to keep up with the old and the new. It's win-win.
