What do you consider as the most emotional Vocaloid song? I'm curious. I know there to be dozens of Vocaloid songs with meanings that touch you in the heart, in good ways, and bad. But what do you consider the one song that stands on top of all the others in that category? And for those wanting my opinion, the one that never fails to pluck at my strings is "Soundless Voice". I've never seen Len in a state of grieving like that.
