For many, "metal" might as well be a swear word. People wrinkle their noses at the term, and treat it like some wholly unapproachable genre fraught with Cookie Monster vocals, overwhelming guitar riffs, etc. "Yeah, yeah, I know metal," you might say. But with all due respect, you probably don't. And neither do I, really—I'm only in the early stages of an appreciation I can tell is going to take a while to fully develop. Metal is a complex beast, far too varied to be pigeonholed into a simple description. Its sub-genres, from doom to thrash to sludge to so many others, open up a huge realm of possibilities. If you don't like one particular kind, there's a chance you may like another. Check out the playlist below for 10 arguably-metal songs. If you like what you hear, plug the bands into the All Music Guide or one of any other myriad websites to get some more suggestions. Before long, you might just be throwing up the sign of the beast with the black-clothed, wizard-bearded, tattooed masses.
