Hey there I hope this is the right forum for this question... Anyways, I am looking to add a button so viewers can simply press the 'play' button to play a certain soundtrack. Here is an example: http://teenscoop.wordpress.com/2007/12/28/listen-jonas-brothers-when-you-look-me-in-the-eyes/ - at the bottom of the post. I think it has to be something else than javascript because wordpress doesn't allow it.
You cannot do it with javascript. Easy to do with flash (streaming audio included). google for flash player and you should find lots of results
yes there are many flash players which you can just use on site without even putting any file Regards Alex
