Can't connect Spotify to Chromecast

[Zent3r]

Hi people, I bought a chromecast few days ago, and I can use it with youtube, soundcloud, and other apps in my android, but when I select the Chromecast as a device from Spotify, the loading screen appears but after a few seconds it just disappear, I tried this several times and nothing happens, why Spotify isn't loading while Youtube and Soundcloud are working perfectly with the Chromecast? Thanks.
