last.fm. If you are already use last.fm then simply enable this feature at the preferences screen and enter your last.fm account data. From now on each song that that is playing at the SoundBridge is scrobbled automatically as long as RokuControl is running at your Android phone.
Scrobbling works with any music server, like UPnP and DAAP servers but not with Internet radio. The app has to check the song that is playing at the SoundBridge regularly to get noticed when the song changes. So turning on this feature may drain the phone's accumulator somewhat faster.
