It's A Love Thing

The lyrics describe someone who feels overwhelmed by a new romantic relationship. At first, the speaker is surprised by how strongly they react to the other person; gradually, they become certain that this love is changing their life and want the relationship to last. The repeated phrase “it’s a love thing” gives the song a confident, joyful feeling, though the intensity also suggests some nervous excitement.

Several images express that intensity. The beloved’s look makes the speaker’s heart “burst into flames,” a metaphor for sudden, powerful passion rather than literal fire. The “pounding” heart shows physical excitement when the loved one calls. Saying that the beloved can “turn my world around” means that this person has greatly changed the speaker’s feelings or outlook. “Talking in my sleep” implies that thoughts of the relationship occupy the speaker even when they are not consciously trying to think about it.

The speaker treats strong feelings as evidence that the relationship is right, saying they know “that’s how it’s supposed to be.” This may express sincere certainty, but it is still a personal feeling, not proof that the relationship will last. The lyrics also contain a difficult-to-understand phrase near the end, “I came back from the slave”; without more context, its meaning is unclear, so it is best not to build an interpretation around it.
