             $.ajax({
                              url:spath,
                              method:'GET',
                              xhrFields: {

                                 responseType: 'blob'

                             },
                             success: function (data) {
                                var a = document.createElement('a');
                                var url = window.URL.createObjectURL(data);
                                a.href = url;
                                a.download = filename;
                                document.body.append(a);
                                a.click();
                                a.remove();
                                window.URL.revokeObjectURL(url);
                            }
             });


   });

What I have tried:

$(document).on("click","#saveddownloadingsong",function (event) {
                event.preventDefault();
                event.stopPropagation();
    			
            var spath = $(this).closest("#contentdetails").find("#songpath").attr("namepath");
    	    var sing = $(this).closest("#contentdetails").find("#songid").attr("sang"); 
    	  
    	   var filename=spath.split('/').pop();
    		 
    	    var datastring ='dsong='+sing;
    	 
    		 
    		  $.ajax({
                               url:spath,
                               method:'GET',
                               xhrFields: {
                                   
                                  responseType: 'blob'
                                  
                              },
                              success: function (data) {
                                 var a = document.createElement('a');
                                 var url = window.URL.createObjectURL(data);
                                 a.href = url;
                                 a.download = filename;
                                 document.body.append(a);
                                 a.click();
                                 a.remove();
                                 window.URL.revokeObjectURL(url);
                             }
              });
    		 
    		
    });

You can either use raw JS and bind the appropriate event handlers as per this StackOverflow suggestion[^] or otherwise consider using GitHub - likerRr/jq-ajax-progress: jQuery plugin that adds support of `progress` promise[^] to add the progress support to the existing $.ajax() method.

Just be aware that in both instances it's dependent on the hosting server to provide the Content-Length HTTP header. And also make sure you're not using this with file sizes which are too large as this binary data gets stored in RAM before it's serialized to the content window.
