The song "Sun Comes Up" by Hank Williams III is about a person who is struggling with the loss of their best friend. The lyrics describe how the pain began the day she left him, and how he has been unable to move on from her departure. The song talks about the memories of the past racing through the person's mind, just like a train on an old track, implying that the memories keep coming back to haunt him. The chorus of the song talks about how the sun comes up but the person won't go down. This means that even though life goes on and time passes, he is unable to let go of his pain and move forward. He is too far gone to start turning around and he feels like all the good times are gone and everything has turned bad since he lost his best friend. The song also talks about how the person has turned to drinking to help ease his mind, but it doesn't seem to work. He has made a new friend called misery and he is unable to escape the feelings of sadness and loss that his friend's departure has caused. Overall, "Sun Comes Up" is a mournful and melancholic song that speaks to the pain of losing someone dear to us and the difficulty of moving on from such a loss.
