it looks this. ca drag , drop below audio tags top

enter image description here

in drop function, @mouser said, path of source element. data variable contains id of audio element, have go source element since there src attribute need. function be:

function drop(ev) {                  ev.preventdefault();                 var data = ev.datatransfer.getdata("text");                  ev.target.src = document.getelementbyid(data).getelementsbytagname("source")[0].src; }

the bad thing if have multiple source elements (for crossbrowser compability), pass wrong source url since element position hardcoded. suggest take this answer
