// Windows browsers (except for Internet Explorer) will play back the file with the Windows Media Player *plugin.* Internet Explorer will use Windows Media Player.
// Non-Windows browsers will play back the file with their standard audio handler for the MIME type audio/mpeg. On Macs, that handler will usually be QuickTime.
