Since you have printed the the res object as console.log(res) inside the subscribe method, check the browser console and notice that Object written there. This means that the value res is an object and it contains key : value pair. So when you try to access console.log(res.devicePlaylist[0]); then you will not find that printed in the console since res do not have a key named devicePlaylist. Thus, devicePlaylist is inside the key Response of res. So, you need to access it as,

res.Response.devicePlaylist[0]

And, since devicePlaylist is an array (also displayed as an array in the browser console), you can use the index value 0 until the array devicePlaylist contains at least one element. Otherwise, you will get undefined if the array is empty.
