Serious question: how do I learn to like bands like Amon Amarth?

I mostly listen to power metal. Powerwolf, Sabaton, like that.

I have never had an appreciation for... Vocal fry? Is that the right term even? When the vocals just kinda sound like growling and are mostly incomprehensible.

I hear people rave about certain bands but when I try them out and their vocals sound like angry screaming and bear noises it just turns me right off, and I'm not sure if that's a me problem or what.
