My experience with Spotify has been generally horrible. I often listen to music on my Chromecast, but no matter what I do, Spotify will get stuck on connecting and never play whenever I tried to cast. This is a common, Spotify-side issue that's been plaguing the app for years and NEVER gets solved. When I manage to connect, sometimes Spotify will randomly disconnect and play on my phone. This is ridiculous. Not to mention the terrible Galaxy Watch support that never goes anywhere.
