Google (s GOOG) is getting ready to roll out Pandora (s P) support for its Chromecast streaming stick any day now, and it has already started to update the Chromecast website with references to Pandora’s app.

Google first announced that Pandora was going to support Chromecast when it launched the TV streaming stick back in July, but neither company was able to share a launch date for the app at the time. Now it looks like that launch is imminent: A closer look at the source code of a web page listing supported apps reveals this metadata description:

“Chromecast is the easiest way to enjoy online video and music on your TV. Plug it into any HDTV and control it with your existing smartphone, tablet, or laptop. No remotes required. Cast your favorites from Google Play, YouTube, Netflix, Hulu, Pandora and Chrome to your TV with the press of a button.”

The CSS code used to mark up the page also contains numerous references to Pandora.

Google had announced Chromecast support for a number of additional apps in July, but since only added support for Hulu Plus to the streaming stick. It’s unclear when exactly Pandora support will roll out, but I’ve heard from multiple sources that the platform would get support for at least one more app before the end of October. I asked both companies about their plans, and spokespersons of Pandora and Google told me that they have nothing new to announce at this point.

Google has scheduled a press event in New York Thursday, but Google might not necessarily make any Chromecast announcements at that event because it has been billed as Google Play-related.

Independently of the Pandora launch, Google seems to be testing a number of additional features for Chromecast, including the ability to beam presentations straight from Google Drive and YouTube video playback from third-party websites.
