The song "What is Love?" by Howard Jones is about the nature of love and the doubts that can arise in a relationship. The lyrics express the idea that love is unconditional and that it is possible to love someone even if they do not love you back. The song also suggests that love involves accepting people for who they are and allowing them to be themselves, even if it means letting them go. The lyrics ask the question "What is love anyway?" and suggest that it is a complex and elusive concept that is difficult to define. Overall, the song encourages listeners to embrace love and to not be afraid to express their feelings, even if they are not always reciprocated.
