The new channels/radiotray.py plugin allows to bookmark stations from Streamtuner2 directly to RadioTray (or now Radiotray-NG).

See also the configuration options, on how Streamtuner2 maps stations onto RadioTray bookmark <groups>.

"root"	is just meant for the old Radiotray format.
"group"	tries to fit genres onto existing submenus.
"category"	maps ont existing submenus just from the channel category.
"channel"	instead creates new Shoutcast - Rock submenu entries.
"asis"	will transfer the literal station genre (or list of genres).
"play"	for RT-NG to stream instantly (no bookmarking)

new Radiotray-NG

The currently maintained version of RT is https://github.com/ebruck/radiotray-ng

• Issue: #92 brought support for the direct "play" option already.
• Saving is done directly into radiotry-ng/bookmarks.json.
• A DBUS mode might come later (might be difficult to incorporate into the main app).

old Radiotray

The original version is no longer maintained.

It did require a patch for RT however, so it accepts the proposed DBUS request.

If you want to apply it manually, find /usr/share/pyshared/radiotray/DbusFacade.py and add following snippet:

   @dbus.service.method('net.sourceforge.radiotray')
   def addRadio(self, title, url, group="root"):
       self.dataProvider.addRadio(title, url, group)

Add it after playUrl or something. Just take care to keep it coherently indented.

I've opened a feature request #242 for this.
