unchanged melody的中文意思是“不變的旋律”，其歌詞如下：
As time goes by, everything changes,
時光飛逝，萬物皆變，
But the melody inside my heart,
但那首旋律卻深藏我心，
Remains the same.
從未改變。
Like a whisper in the wind,
如風中的低語，
The melody floats and fades,
旋律飄蕩漸逝，
Yet it never leaves my mind,
但它從未離開我的腦海。
I remember when I first heard it,
我還記得第一次聽到它時，
It filled me with such wonder,
那時我心中充滿了驚奇，
And now, so many years later,
現在，多年過去，
It's still the same.
它依然如故。
Chorus:
不變的旋律，
A constant companion,
永恆的夥伴，
Through the highs and lows,
在高低起伏中，
Through the joys and tears,
在喜悅和淚水間，
It remains the same.
它依然不變。
Each day brings new changes,
每天都有新的變化，
Yet the melody inside my heart,
但那首旋律深藏我心，
Remains the same.
從未改變。
Verse 2:
Through the years, I've tried to let it go,
這些年來，我曾試圖讓它離開我，
But it's always there, haunting me,
但它總是縈繞在我心頭，揮之不去，
And now I realize,
現在我明白了，
It's not the melody that changes,
不是旋律在變，
It's the one who listens.
而是聽曲之人。
