Toastify adds some missing functionallity to the Spotify client(Windows only).
It shows a popup, toast style, dialog on track change and it allows you to use global hot keys for Play/Pause, Next, Previous etc. Toastify is developed using C# and WPF.
Sporting better album art, more reliable Toasts and the hotkeys that keep you coming back for more Spotify music, this is the best version of Toastify yet.
