I don't think the API on the FM Transmitter is documented either.. so if someone can show me how I'd love to. I know there's a problem with scrobbling to like Last.FM because the scrobbler apps use the metadata/id3 tags of the mp3 to scrobble.. and there is zero information in the stream from Pandora. The Artist and Album come separately but not part of the MP3. So if the FM transmitter works the same way, probably not .
