"My Happiness Song Lyrics" in English might be:
My happiness is a melody
That plays in my heart every day
A song of joy and fulfillment
That never fades, never dies
It's the sweetest melody
That ever played in this world
A melody that brings me peace
And joy that never ends
It's the rhythm of my life
The beat that I live by
The melody that brings me happiness
Every moment, every day
This happiness is mine to keep
Forever in my heart it'll stay
A melody that never fades
A song of joy that never dies.
