Some videos can be muted so that you can use music instead of their default sounds. This is a great way to create an MTV like of a production and with the right tune for the theme of the video, you are sure to draw a round of applause after everything has been compiled and presented.
That is why it would be best to be up to date with latest musical tunes. Old and new have their way of spicing up the video project and once you do, you are bound to blow life into the video rather than relying on the raw video with nothing to show.
