Bruno Mars' popular "Just the Way You Are" includes several examples of figurative language. Here are two to get you started.
In the first verse, Mars says:
Oh, her eyes, her eyes
Make the stars look like they're not shinin'
This is an example of hyperbole, or over-exaggerating an idea to get a point across. Mars' lover's eyes are not actually brighter than the stars, but Mars claims they are to emphasize how beautiful they are. He is trying to say that the word "beautiful" is inadequate to describe their level of beauty.
In the chorus, Mars employs personification by ascribing human characteristics to an inanimate object.
And when you smile (smile, smile...)
The whole world stops and stares for a while
Mars claims that when his lover smiles the world "stops and stares." The earth cannot stop and stare; this is something a person would do. This could also be considered an example of hyperbole. The world does not actually stop when she smiles, but her smile is so captivating that Mars feels as though the world around him has frozen.
