I know this is unrelated, but what's so great about Europe? (I'm not trying to sound all nationalistic here, I swear) They didn't give the world The Velvet Underground, Swans, the Pixies or any god tier emo bands like Sunny Day Real Estate, Knapsack, Texas Is the Reason, and Mineral. In terms of metal America and Europe are at a stalemate, both had amazing death metal scenes (Florida and Sweden), Norway had black metal, America had southern sludge, and both have great doom bands. But America had nu metal, which I dislike, and Europe has power metal, which I also dislike. Either way, you're just limiting yourself by ignoring a region that is home to a lot of great music. I personally don't care where a band is from, as long as they're good I'll listen to them.
Back on topic:
I find that sometimes I don't really like an album when I first listen to it. It's not that I don't like it, it just means it's a grower. Trust me, once an album grows on you, you get hooked onto it. Sometimes, there are albums that are addictive from the very start and then you just want to listen to them 10x a day.
