Media keys wont control Spotify

[melissa9219]

Hi,

My media keys have stopped working with Spotify.
I have iTunes open and normally my media keys will control that instead of Spotify unless I have the Spotify window open then the media keys control Spotify.
Now even if I have the Spotify window open the media keys will no longer work with Spotify at all.

Is there a way to get the media keys to work with Spotify specifically, and not iTunes and other apps?

Thanks.
