I hope it's possible to access the elements of this site. http://ift.tt/1k5qFSa

I really have the feeling it's possible to access the elements of this site http://ift.tt/1GP7Anu. I'm experimenting to make keyboard shortcuts to the site. I wanna access/control the play/pause button and this: http://ift.tt/1MLBcCq While I'm in another tabs or I'm not there in thelistenonrepeat.com site. If it is possible, could you please tell it to me how? I know some web languages (javascript and html). THANKS!
