Why doesn't the West have access to Japanese music, especially vkei?

In the West, even today, Japanese music doesn't reach here except for the most famous ones, a good example is Plastic Tree or any other famous Japanese band, it's super rare for a Japanese band to have their complete discography on streaming and some bands even end up getting lost and here we can't even listen to them, I think a good way to get around this would be to visit Japanese blogs and websites, because we rarely have access to them.
