Background music on the site

Question

PHP

Hello!
Please advise how to implement music on the site.
The main task is that when moving through the pages it would not be interrupted, but would continue to play. Perhaps some offline tabs that are inaccessible to the user's eyes. I've never experienced this before, but now I need to!
Thank you!

Answer 1

Just be sure, hear, ALWAYS make it possible to turn off the music in a conspicuous place.

Answer 2

1) iframe
2) AJAX + History API navigation

Answer 3

1. Cookie
2. Local Storage
Every X seconds update what is being played and in what location. The task is not difficult to use <audio>. developer.mozilla.org/en-US/docs/DOM/HTMLAudioElement to help you.
