I'll Follow The Sun by The Beatles is a tender song about accepting the inevitability of change and choosing to move forward despite the heartache. The song reflects themes of love, loss, and the realization that sometimes one must forge a new path to find happiness. One poignant moment is when the lyrics say 'One day you'll look to see I've gone, for tomorrow may rain, so I'll follow the sun,' highlighting the narrator's decision to leave before things get worse, seeking a brighter future elsewhere.
