One song with a simile in it is "Love Like Heaven" by Sarah Buxton. The line "a love like heaven" is a simile. It shows how she wants a sweet, pure love like heaven.
Another song with similes in it is "To Find A Heart" by Big Kenny. The line "and when it hurts like Hell, that's when you know it's real" shows a simile by saying the level that love hurts, and when it feels like Hell, then you know it's real.
