I've been paying for Spotify premium for about a year.  Today, I cancelled my subscription.  The in-ability to transmit wirelessly to my audio/video system is the main reason for canceling.  Chromecast is a HUGE leap forward in Android technology.  Airplay for Apple is awesome and now Android can have this ability via Chromecast.  Yet Spotify won't even acknowledge postings on Chromecast.  

I just got done testing 3 different Miracast devices.  Just because I really want wireless access to my audio/video system.  Unfortunately, Miracast has many issues.  Google Music via Chromecast is light years ahead of Miracast.  I hate to learn a whole new platform with Google Music, but the convenience outweighs the inconvenience of a new platform.

Another issue is not being able to delete Playlists.  Really...this is just an elementary feature.  I hate having my Android's Spotify app so cluttered up with useless playlists that I created to test or just needed for temporary purposes.  

Just wanted to give some feedback to my cancellation.  Google is now getting my monthly fees.
