There seems to be a fair amount of issues with Chromecast Audio and Spotify. But something I have yet to find any word about are the queuing issues with Chromecast Audio and Spotify. Playing from an album or playlist seems to work fine, but when you start adding tracks to Up Next/Queue, Spotify will inevitably end up repeating tracks, or queue random tracks. And also Spotify will show the incorrect song but be playing the right song sometimes, and sometimes vice versa. Really buggy. I can't tell if this is because multiple devices are simultaneoulsly looking at my spotify account, which was never a problem when I was just using an extra tablet. It also still does not account from the seemingly random songs that appear on my queue. I know once you start casting from a device, you can then start controlling it from desktop Spotify. But you cannot initially cast to CCA from desktop, which is an issue that's been on the table since the CCA release.
