Emotional Connection

How do you console someone who is super bummed about a musician dying, that they've never met... I understand music speaks to us all differently, and somehow there's this emotional connection with an artist even though we never meet them. We still feel like we know them for some reason. It's the whole John Lennon or Kurt Cobain thing too. But still, I don't know what to say. Or how to make it better. Sucks. I just sat there helpless. Not a good feeling.
