Disable "Play"-button to open iTunes

Question

Hi,
I want to disable (or reassign) the "Play"-button on the keyboard (Macbook Pro) and the middle button on the headphones to stop them from opening iTunes. Either by just disabling the buttons from opening iTunes or to reassign them to open Spotify instead.
The media keys on the keyboard (play, forward, back) all work in Spotify as long as the application is running, if it's not the play button opens iTunes.
The headphones middle button however opens iTunes even if Spotify is running.
I've seen that there are a few scripts and hacks out there but none of these seems to work in Mavericks.
Any ideas on how to fix this in Mavericks?

Pigeon, you may access your button inside RDH_mc from your main timeline using dot syntax, so, instead of adding the eventListener to your close_btn on your RDH_mc timeline, try doing this in your main timeline instead:
RDH_mc.close_btn.addEventListener(MouseEvent.CLICK, onExit); //this will access close_btn inside RDH_mc.
function onExit(e:MouseEvent):void {
     removeChild(RDH_mc);
Doing so you can get rid of that listener you're adding to RDH_mc directly.
Hope it works!
edit: oh, also, inside your openEvent1 function you have to addChild(RDH_mc) first and than play it.
Note that inside your onClose function you're removing it but it seems you're not adding it anymore. That's probably why your button will work only once. The second time you try it, it's actually "playing" your movieClip, but you can't see it because it's not on the displaylist anymore (you removed it the first time you pressed the close button).
