+    Notes
+    Windows 8 supports by default mp3, wav, wma, cda, adx, wm, m3u, and wmx. This
+    can be expanded on by installing new codecs, but Media.prototype.play() needs
+    to updated. 
+    ##Todo
+    find better method to implement filetype checking to allow for installed codecs
+    record audio
+    implement more error checking
