While playing any other radio network other that Sirius, if I use the CLI (telnet <host> 9090) like this:
status 0 1
00%3A04%3A20%3A12%3Aa6%3Aaa status 0 1 player_name%3Asqueezebox player_connected
%3A1 player_ip%3A192.168.0.15%3A31065 power%3A1 signalstrength%3A81 mode%3Aplay

Here you see the title & artist attributes are properly set for this radio station.  Unfortunately, when you do that while Sirius is playing wont see any data passed through.  This is the only radio network that doesnt do this.  The last time I saw artist-title data being passed to CLI was in SqueezCenter 6.xx and respective Sirius Radio backend servers.

This issue is critical to any 3rd party, open source apps that depend on this data.
