This is the main screen for the Pandora app on Windows Phone. Recently played stations are shown as a small grid of album art, with the most recent station or the song that's currently playing in the biggest space.
Once you launch a station, you'll see the playback screen, which shows the current song and artist information. You can up-vote and down-vote, pause and play, and skip songs from the controls at the bottom.
The app comes with a live tile that shows the Pandora logo and flips to reveal the song that's currently playing (shown above, bottom). You can also pin stations to your start screen (shown above, top).
