I'm late to the party but I was first exposed to Miku early last year with this video and I am continually moved to say the least. I believe she makes us feel even more human when listening to songs like this, its amazing. Not wanting to allude to Sharon Apple but it's good to be alive in this generation. Sorry if this is a repost:

Shame her concert this year was such a comparative flop, though Miku and her composers just got a lifelong fan.
