Music to your eyes.
What makes one song more successful than another? Its music, of course. But also its charisma. In both senses of the word. Its media distribution and its look. Yes, its look. Ever since we started carrying MTV around with us on our smartphones wherever we go, audio without video has become almost unthinkable. It's a must. But a music video, after all, is also an opportunity to give a track even more punch. And if the budget is limited? Doesn't matter, creativity never is.
