Metal is all thats left in the music industry. The screaming adds brutality , excitement and energy, especialy live. But its not all about the vocals. its got killer Riffs and rapid drums. Emo is what i dont like -.- but back to metal, the vocals do have meaning anyways, and its not like R&B where its just love stories over and over, its about personal stuff, whores on the planet, murder, death, rape, relationships and everythin pretty :)
