It would be nice to have an Global Hotkey so you can pause/play your music while browsing and not switching between screens. Or when you are gaming and you want another song but you don't want to alt tab and stay idle, a (customizable?) Global Hotkey(i.g. ctrl+shift+right) would be such an great improvement in the usefulness of Spotify.

Thanks for coming to the Community, and adding your vote to this idea.
After discussing with the right teams we've decided not to implement global hotkeys on Spotify.
Thanks for continuing to share your ideas and giving us feedback in our Idea Exchange.
