What are the potential drawbacks of having background music on a website?

Having background music on a website can be distracting and annoying for visitors, especially if they are unable to control the volume or turn it off. It can also slow down the loading time of the website, leading to a poor user experience. To solve this issue, it's best to give users the option to choose whether they want to listen to background music or not.

<?php
// Check if the user has opted to listen to background music
if(isset($_COOKIE['background_music']) && $_COOKIE['background_music'] == 'on') {
    // Include code to play background music here
}
?>
