The rule of thumb with media is ALWAYS allow users to decide. For this reason "Autoplay" of audible media is not supported by all browsers. Also, when you take away player controls, many people including myself will never know your site contains media. We see only a static image with no way to play it.

This way, the play button is obvious to everyone.
