"It Must Have Been Love" 是羅克塞特的一首歌曲，但這首歌並不是他們的代表作，因為他們的知名作品如 "Lucky" 和 "C'mon C'mon" 更有影響力。然而，這首歌的歌詞可能涉及到愛情和懷念。以下是我對歌詞的大致理解：
It must have been love
It must have been true
'Cause I've never felt a thing like this before
And now I'm feeling insecure
You say it couldn't last
But I've been waiting for so long
For you to come back and say
Baby, I'm sorry, and I love you
But it must have been love
It must have been fire
I ain't looking for a lover
Just something to believe in
Now I'm left standing alone
And it must have been goodbye
So let me go
Oh, I can see the fire in your eyes
And all I can think of is the times we cried
It's gotta be what it was before
It must have been love
Now baby I just can't pretend
'Cause every time you call my phone
And tell me we were something real
And I wish you didn't have to pretend
You said I could call you mine
And now your hanging up the phone
Baby, why won't you face the truth?
We both know that it must have been love
Oh, but it was just a short affair
You'll always be in my heart, forever more
It must have been love
Oh, but now you just don't care
So baby let me go, oh...
(It must have been love) Oh, yeah...
這首歌的確存在一些感傷和懷念的元素，但我還是強烈建議您查看原始的歌詞版本以獲得最準確的信息。我還可以幫您解讀其他歌曲的歌詞，請問有其他需要幫助的嗎？
