Metaphors and Similes

All songs have a form of metaphors or an actual metaphor or two. Metaphors in many peoples eyes can mean one thing or many other things. Similes I think are a bit misguiding when it comes to trying to describe something with a simile. Metaphors can help describe something to someone way easier then a plain old saying can for example " A Stairway to Heaven" to one person can mean an easy way to seek savior or simply a stair case in the clouds that supposedly leads to heaven. A simile to me can be confusing when it comes to describing something because something simply as an ordinary boring object or stupid subject can be used to describe something.
