Chromecast wont play or only plays one song

Had this problem forever. It either randomly wont play songs or if Im lucky it plays one song then stops. Useless on iPhone even though I love the service overall, just wish this would get fixed. Its a pretty hard fail when a Google app cant properly interface with a Google device, and this has been an issue for a long long time
