Ah got it to work. I think Spotify just needed a reboot. Thanks.

Is there any way to do a drop down sub-menu for a certain tab?

I don't think that is an option. We Are Hunted uses a drop down menu but they actually aren't using the Spotify bar. They redid the bar themselves and you can actually pull it from them if you inspect their app.

Thanks man. :)
