I know diddly about HTML, CSS, ASP, PHP and all that stuff. Okay, well next to diddly.
I managed to create a track though, after trying unsuccessfully for an hour.
I put a version into MP3 and a version into SWF
I don't know how these will work, but both are working for me (no surprise because I made them on this machine). I'd be interested in knowing if they cause any problems.
Here is the SWF version: http://cherrytap.com/play_track.php?t=6328461
