Tune In doesn't provide that type of integration.

But you can get the info about what is playing via the website or mobile app.

In the case of Android,  you would hit the track  button on the player and select the channel streaming via tune in.   
Can do the same via the website as well.

I have just set up my android phone so I can listen to RP through my Sonos speakers, having added RP as a radio station using the TuneIn link in the Sonos app, but the only information I can see in the Sonos app is the name of the song and the artist that is playing. Ideally I would like to be able to see all the other info that you can see if you click in the RP app on the song that is playing - artwork, lyrics, song and artist details... When I was looking into how to link RP and Sonos I imagined it would be done by starting in the RP app (and not Sonos) and selecting my Sonos speakers as the output device like you do in Spotify by clicking on 'devices available', which would then allow me to see all the other info. Is there any way to do this? Have I missed something obvious? Am I just being stupid?!
