As Time Goes By

The lyrics express confidence that some parts of love remain familiar even as the years pass. People still kiss, sigh, declare their love, feel passion and jealousy, and struggle for a relationship. The mood is warm and reassuring, though the mention of conflict gives love a more dramatic edge.

“Fundamental things” means basic or essential parts of life; here, it suggests that time and change do not erase familiar human feelings. Moonlight and love songs represent romance as something that never goes out of fashion. The phrase “a case of do or die” is an idiom for a situation that feels extremely urgent, making the pursuit of love sound like a high-stakes contest.

The song presents love as both tender and intense, involving devotion as well as jealousy and struggle. Its claim that men and women need one another is stated broadly, as a traditional view of romance rather than a rule that must apply to everyone. “The world will always welcome lovers” may mean that love remains recognizable and valued across time, though the lyrics do not explain exactly what that welcome looks like.
