When spotify has been running about half an hour it gets pretty much impossible to change track/playlist, end the application or just switch away from it. It always ends up with the tv having to restart, sometimes spotify is "broken" some time after having restarted the tv. If you navigate away from spotify after 2-3 songs, it's just fine.
I have tried uninstalling and reinstalling, no change. This is the only app that is causing me problems on the tv.
