Lyrics:

[Intro]
Do-do, do-do (No, no, no), oh-oh (Oh)
Do-do, do-do, oh-oh (Oh my god)
Oh-oh

[Verse 1]
Sweet lullaby 'til our love ran empty, yeah
Let the pain live on, a reminder that I can feel, oh
Can't look up 'cause she's blind by envy, yeah
Precipitation when she's around, it can't be real

[Pre-Chorus]
All I see is smoke and mirrors
I ignore it 'cause she's a bad bitch
Then the smoke gets clearer
And then she comes and gives me the passion
Attraction, she's the definition of malice
Such a beautiful distraction
I'm losing sight of the backend, oh

[Chorus]
I can't lose myself in her song no more
I just can't lose myself in her song no more
Damn, it's such a sweet lullaby
Do-do-do (Oh), oh-oh (Woah, woah)
Do-do-do (Oh), oh-oh (Woah, woah, woah)
Do-do-do (Ooh), oh-oh (Do-do, oh no)
Do-do-do (Oh), oh-oh (Oh)
Oh-oh

[Verse 2]
Traveled abroad but she's from the West Indies, yeah
A flame you can't turn off
See it burn through a hundred years, oh
Trouble follows whenever she's with me (Do-do)
In the end, she ends up right here in my bed

[Pre-Chorus]
All I see is smoke and mirrors
But I ignore it 'cause she's a bad bitch
Then the smoke gets clearer
And then she comes and gives me the passion
Attraction, she's the definition of malice
Such a beautiful distraction
I'm losing sight of the backend, oh (Ooh, I can't)

[Chorus]
I can't lose (No, I can't) myself (Myself) in her song no more (No more)
I just can't lose (No, no) myself in her song no more
Damn, it's such a sweet lullaby
Do-do-do (Oh), oh-oh (Woah, woah)
It's such a sweet lullaby
Do-do-do (Play it for me, ooh), oh-oh (Oh, woah)
It's such a sweet lullaby
Do-do-do (Oh), oh-oh (Sweet, do-do, oh)
Do-do-do (Oh), oh-oh (Oh)
It's such a sweet lullaby
