This is pretty much a more public, more awesome version of what I do in the kitchen--my roommate is generally the only witness. The best is from about 0:56 to 1:04.
Dance is pure expression: there are no words to limit to one interpretation or cause self-consciousness because emotions can only be inferred. Dance can invoke joy, self-mocking, yearning, frustration. And if you make it interesting and musical enough, people will watch and enjoy--it transcends the boredom created by talking about oneself. An art form, for sure, one which I do poorly, but I revel in regardless.
And music--I feel like I should sing it here!--music has a primal power that defies explanation. I'll try a little, but I know I'll come up woefully short. When I listen to the best music, if it's joyful, I experience my deepest joy. That sounds wrong, as if my joy in being human and love and relationships is outdone by a sensual experience. But great music makes me experience all that love and pain in heightened form; so listening to great dance music is incredibly visceral--I don't have to think, and it may be the only time I really get out of my head and let myself just feel. And it feels wonderful.
And here's the link to the Billy Idol song of the title, just because I always forget how great it is.
