Many people tend to visit websites in public places and most times cannot play music. If you have music that auto starts and the person draws unwanted attention then that embarrassment is forever associated with your website and they may never return.

Not to mention that sometimes they have their speaker on very high from the last time they were listening to music and your music can give them a heart attack on the spot if they were not expecting it.

So, save some lives, don’t auto play your music or video on your website.
