In order to ask the questio0n, I need to explain the context:
I was in discussion with a friend(Annie), talking about one of our friends, James.
He was filming a video documentary for his PhD thesis about Chinese music. Unfortunately, we lost him about 3 years ago due to stroke.
During the discussion, I mentioned a concept in Chinese:时代相关性, which means the documentary has its relevance to today's world. In another words, the documentary makes perfect sense in the current world, but may not be relevant after 2 decades or whatever the time could be.
I searched online and found 2 words:
Relevance and Correlation
So here is my question:
In this context, which one fits the best and why?
