Some people simply have an affinity for other cultures. There's no reason to dislike a group of people because they like a part of something for a different reason than you. I didn't really like this bands sound so much but the only reason I even came across them is because they are Japanese. Japan has a great diverse music scene as far as I can tell. Trends and scenes, collaborations, occur in different parts of the globe -and now the internet depending on your blog finding and artist affiliations- so in the end it's all about the music, some people find more in common with people a world away than the people up the road.
