《Signal》的歌詞如下：
91 days
主唱：S.E.N.S
（Verse 1）
Waiting for the rain to wash away
The memories of you and I
The pain inside
Will never fade
But time will heal the wounds
I'll keep on
Holding on to the hope
That one day
You'll come back to me
（Chorus）
91 days away from you
Days that feel like years
Without you here with me
Will I ever see you again?
（Verse 2）
Through the clouds and through the rain
Through the pain and though the pain
I keep going on
Just gotta keep my head up high
Until I find you again
（Chorus）
91 days away from you
Days that feel like years
Without you here with me
Will I ever see you again?
（Bridge）
I'm lost without you
My heart's so empty
I can't sleep without you here with me
I'm holding on to every hope
That one day you'll come back to me
Back to me, oh yeah
（Chorus）
91 days, can't get over you
Without you here with me, with me, with me
Every moment without you is so hard to take, oh yeah
Will I ever see you again?
Yeah～ Yeah～ yeah～ yeah～ yeah～
