Cough Syrup--Young the Giant

        There were many poetic devices in this song.  The first one I noticed was, "A wet world aches for a beat of a drum".  This one was an example of personification.  The song also has symbolism, like when it say, "I'm waiting for this cough syrup to come down" or "The fishes in the sea are staring at me".  Another device was, "If I could find a way to see this straight I'd run away", and I thought it could maybe be a narrative.  It kind of tells a story, because it says there's a chance that he'd run away.  It could also be a simile I suppose, because it compares his problems to being so overwhelming that he'd run away.  The last one states, "Coming up out of the blue", and it is an idiom.
        This guy feels lonely, because he probably broke up with his girl friend.  His heart aches for her just like the wet world is aching for a beat from a drum.  He wants to get back together with his girl friend, but he's waiting for her to want him back.  Just like he's waiting for the cough syrup to come down.  Later in the song it looks like he's beginning to live a new live and forget about his old girl friend.  He decides to find something or someone better.  He's "Coming up out of the blue".  He's forgetting the past and finding a cure for himself instead of waiting to see if his old girl friend will do anything.
