small audio sampler/player

I'm building a site for a client that wants a small audio sampler in their site, it will play 10 sounds in mp3 format and the user will have the capacity to download the individual sounds in .wav format, these will be stored in zip files and called using the geturl function.

The sounds need to play independently of each other, so if a user clicks on sound4 for example, any other sound will cease to play. I'm thinking of using the stopallsounds function as the first piece of script on each button that launches the streaming sound, will this create any problems?

What i'm unsure of before i beign building the player is how i should put it together for optimum usability. Would it be best to load all the textual info from an xml file and manually code the buttons or would it be possible to make it in such a way that the xml file, (or a php file?) dynamically creates the necessary play and download button for each sound in the xml. I've looked at using id3 but since the data cannot be loaded until the sound has downloaded i dont think this will work with streaming sounds.

if someone could point me in the right direction and potentially lay out the bare bones of the application it would be hugely appreciated.

Thanks.
