A prime example of this is the song Issues by The Saturdays because by looking at the lyrics to the song, the band refer to the word "heart" a lot throughout the video and at one point in the video, the band are seen standing behind a white fence when the lyric, "I keep building a wall over my heart" is heard. This is possible symbolism of the metaphorical wall between the men and their hearts.
Another example, is at the end of the video where the band can be seen standing around a fire. This could give a polysemic message that the band are trying to forget their "heart-breaking" memories.
Here is the video for the song:
