The song "Wheel of The World" puts a spin on all life's emotions. The last song in the collection of songs by Carrie Underwood's "Carnival Ride," it focuses on all of life's obstacles. Love, new life, etc. The "wheel" in the song is the force that keeps everything moving through the emotional obstacles. In the song, a roller coaster is used to resemble peoples' lives; Roller coasters have ups and downs, and twists and turns, as do our lives. Throughout the entire song you'll find things you can relate to. With all these qualities of this song, I rated it as a 5. I know it's the highest, but it's one of the most deserving songs! It's one of the best!
