Lyrics Format (MiniMax Music 1.5)

Use structured tags for song sections:

[intro]
(Soft piano melody)

[verse]
Walking through the city lights at night
Every shadow tells a different story
Searching for a meaning in the dark
Finding hope in unexpected places

[chorus]
We rise above the noise
Breaking through the silence
Every heart beating as one
Together we are stronger

[bridge]
When the world falls apart around us
We'll find our way back home

[outro]
(Fade out with gentle strings)
