Ultimately, sharing is something people want to do as a natural inclination. I like this band, so I want you to like this band, so here's their music. I personally have found the vast majority of the music I love in this fashion.
I love passing on my love of music to other people. I've run private MP3 servers before. It brings me much joy to share music and then talk about it.
I don't really know what these large verdicts do. They are still effectively like being hit by lightning, it's so unlikely it will happen to you.
