> "Whatever app I use to play music needs to support chromecast audio." If you can't find something pre-built that fits your specific needs, you could perhaps "quick and dirty" script yourself up something using "Cast All The Things" [catt@github][0] to talk to your ChromeCast devices, and maybe "Beets" [beets@readthdocs][1] to manage play / playlist commands and management of the music library itself, presuming some Python scripting skills on your part, or a willingness / interest in learning said skills. Other language / library pairs exist as well, if Python's not exactly in your "bag of tricks". - [0]: https://github.com/skorokithakis/catt https://github.com/skorokithakis/catt - [1]: https://beets.readthedocs.io/ https://beets.readthedocs.io/
