Post a picture, and with the picture, post a link to a song that you think fits the picture somehow. Perhaps you think the theme of the song fits the theme of the picture, or perhaps the picture just reminds you of the song somehow, doesn't matter as long as there's some link between the picture and the song in your mind.
