There are a lot of audio/music players that are either WP plugins or work with WP, but I don't see that they do exactly what I'm looking for. I want to be able to play an audio file automatically when the site loads, as a sort of background music, with the only control a "turn this off" button - no play/pause, no track info etc. (I'm vehemently against this sort of online Muzak, but my client is insistent.)
Is there a good way to do this?
