Hi,
So if I've not mistaken... you need to build a script hosted / installed on a CDN page which serves / delivers songs from another host you own?
Well it wouldn't be possible if you only use front-end javascript scripting (on CDN); a back-end PHP may also need to be built (on other host) to support it. Wait... somehow this looks reversed. Usually media like songs are to be hosted on a CDN, not the landing page. May I first look at your current landing page?
Cheers,
