《Sisters Noise》的詞曲作者和演唱者是艾薇兒·拉維尼（Avril Lavigne）。這首歌的完整歌詞如下：
Verse 1:
It's 2:00 in the morning and I'm calling
But you're not picking up your phone
And I can't sleep with all these memories
Trying to find a way to let you go
Chorus:
So what if I don't hear from you today
Sisters noise I'm letting go
But if I try to hold on to you
The whole world will go silent and lay down and play
Verse 2:
When we used to party every single day
It's been a while since I've been around
But I'm still trying to figure out
How to make my mind up and move on
Chorus:
So what if I don't hear from you today
Sisters noise I'm letting go
But if I try to hold on to you
The whole world will go silent and lay down and play
Bridge:
So don't tell me I'm being weak
Just trying to be strong
When my heart's not in it anymore
So tell me it's alright to let go
Chorus:
So what if I don't hear from you today
Sisters noise I'm letting go
But if I try to hold on to you
The whole world will go silent and lay down and play
Yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah
