As Long As I Love by TK (Toru Kitajima) and Koshi Inaba of B'z is a rather contradictory song with a constant push and pull between love and despair, hope and disillusionment.
As Long As I Love themes
Uncertainty and disillusionment: The lyrics express a deep sense of doubt and disappointment not only in life but with relationships. Lines like "Even the things I believe in easily goes up in flames" and "Things do not usually turn out how we want" illustrate a picture of a world where nothing is guaranteed.
The Power of Love: Despite the negativity highlighted, the song also highlights the importance of love. The repeated refrain "As long as I love" emphasizes the idea that love can provide a source of strength and hope, even in difficult times we might encounter.
The Search for Meaning: The lyrics explore questions about truth, change, and the future. The narrator(s) is/are overwhelmed by the sheer number of possibilities and there is a struggle to find a path forward.
Holding onto Hope: Despite the darkness, there's a flicker of hope for the narrator(s). The final verse talks about clinging to a cherished memory and fighting for a better future despite it all.
The song is a melancholic high-energy Rock song with a small glimmer of hope. The lyrics express a deep sense of sadness mixed with confusion, but there's also a determination to hold onto love and find meaning in a seemingly meaningless world.
