The song "Thinking of You" by Jars of Clay and SHEL is a melancholy Christmas song about missing someone who is no longer a part of the narrator's life. The lyrics talk about the cold winter air and the memories that it brings. The narrator is reminded of the person they miss when they see snow angels' wings or take out their winter clothes. The chorus repeats the phrase "I'll be thinking of you" as the narrator admits that they can't help but remember the person they miss. The bridge of the song talks about the struggle the narrator faces when they start to believe that they have moved on, as the memories come back to "haunt" them like the Ghost of Christmas Past. Overall, the song is a bittersweet reminder that the holiday season can be difficult when you're missing someone special.
