$.each : A generic iterator function, which can be used to seamlessly iterate over both objects and arrays. Arrays and array-like objects with a length property (such as a function's arguments object) are iterated by numeric index, from 0 to length-1. Other objects are iterated via their named properties. Reference documentation
$.ajax({
url: "system/music_list.php",
dataType: 'json',
cache: false,
success: function(response){
//Check if the response is in expected JSON format.
var flag = isJSON(response);
if(flag === true)
{ response = JSON.parse(response); }
//Iterate the Array using for each loop of jquery
$.each(response, function( index, value ) {
console.log( "Index : " + index + "Value : " + value );
});
} // End of success function
}); //End of Ajax
//JSON format check
function isJSON(data) {
var ret = true;
try {
JSON.parse(data);
}catch(e) {
ret = false;
}
return ret;
}

<div id="dat" name="dat"></div>
<script type="text/javascript">
$.ajax({ url: "music_list.php",
dataType: 'json',
cache: false,
success:function(response) {
for( res in response) {
document.getElementById('dat').innerHTML+=response[res]+"<br/>";
}
}
});
</script>

Please use below code :
$(response).each(function(key,value){
console.log(value);
});
Here each loop of response array and value get ('jazz',rock,...etc).

Try a for loop
to loop the records
$.ajax({
url: "system/music_list.php",
dataType: 'json',
cache: false,
success: function(response){
var record;
for(record in response)
{
console.log(response[record]);
});
},
});

You can get array indexes and values by using .each
in jQuery as:
$.ajax({
url: "system/music_list.php",
dataType: 'json',
cache: false,
success: function(response){
$.each(response, function(index,value)
{
console.log(index); // print all indexes
console.log(value); // print all values
});
},
});
