WordPress Background Audio – Continous AutoPlay

Since I don’t have enough reputation to add a comment yet, I read on another website that someone used http://scmplayer.net/ as an alternative to frames/popups which seems to be a little script you can generate and then use on both non-WordPress and WordPress sites (since it just needs to be inserted after the <body> tag).

Or you can self-host the script (source) but either way, you should be aware that there are reported issues with SCM Player at the moment.

So without commenting on whether this script is a good or bad approach, how you apply it to your WordPress install will differ depending on your theme and if you prefer to self-host etc. But it will involve editing of theme files; whether this is your child theme or adding the relevant scripts to your theme’s functions.php
