man trust me thats how it starts i started with Children of Bodom cause you can make out the vocals etc......over time you become more and more accustomed to "death vocals" ...i been listening to heavy shti for 3 years now and the heavier the better ...try this........download a Decapitated song try....3 Dimensional Defect....he does a very brutal(not gutted) death growl and if you read along with the lyrics(i use darklyrics.com) you an make out every word he says perfectly....it almost shocked me how understandable it is....and now i can sing alnog without seeing the lyrics and can usually udnerstand most death vocals unless they are extremely gutteral
