Notes

1. If you want the music to autoplay, you need a service that lets you autoplay the music (for example, Soundcloud has a checkbox for "autoplay" when copying the link.
2. For autoplay to work, the person visiting the website needs to do an action inside(for example, entering the website and then going to the page that has the music [another page])
3. Autoplay music is not allowed by most of the browsers, and it is not supported on mobile devices
4. Make sure you have the rights to use the song in your website
