The song "Sitting On Top Of The World" by Beth Hart & Joe Bonamassa is a blues classic that tells the story of a woman who refuses to let the departure of her lover get her down. The lyrics suggest that the woman was left alone during the summer, while her partner went away. Despite this, she doesn't worry and feels that she is sitting on top of the world. The woman highlights that she had to work on a farm during the summer and had to wear overalls even during Christmas. Even though this was a difficult time, she didn't let it break her spirits. She's proud of herself for persevering through tough times, and now that her partner is gone, she feels just as good because she's still "sitting on top of the world." The woman decides to leave town, as work has become too hard. She plans to catch a freight train down to the freight yard. She's confident that things will work out for her because she's been through tough times before and came out on top. Overall, the song is about resilience and self-reliance even during difficult times. No matter what happens in life, it's important to keep pushing forward and believe in oneself.
