i'm singing my blues 这句话来自哪里,是一张专辑或者歌名吗,或者只是一句心情

这是一句歌词,来自南韩的偶像团体Bigbang的歌曲"Blue",整首歌是韩文的,英文翻译的歌词如下:
[G-Dragon] Winter had passed
And the spring has come
We have withered
And our hearts are bruised from longing
[G-Dragon] I’m singing my Blues~
[Seungri] Used to the blue tears,blue sorrow
[G-Dragon] I’m singing my Blues~
[Seungri] The love that I have sent away with the floating clouds Oh,Oh
[G-Dragon] Aye-Oh
Under the same sky,at different places
Because you and I are dangerous
I am leaving you
One letter difference from ‘nim’
It’s cowardly but I’m hiding because I’m not good enough
Cruel breakup is like the end of the road of love
No words can comfort me
Perhaps my lifetime’s last melodrama
Now its final curtain is coming down
[Daesung] I was born and I met you
And I have loved you to death
My cold heart that has been dyed blue
Even with my eyes closed,I can’t feel you
[TaeYang] Winter had passed
And the spring has come
We have withered
And our hearts are bruised from longing
[G-Dragon] I’m singing my Blues~
[Seungri] Used to the blue tears,blue sorrow
[G-Dragon] I’m singing my Blues~
[Seungri] The love that I have sent away with the floating clouds Oh,Oh
[T.O.P] I feel like my heart has stopped beating
You and I,frozen there,after a war
Trauma that has been carved in my head
Once these tears dry up I will moistly remember my love
I’m neither painful nor lonely
Happiness is all self-talk
I can’t stand something more complicated
It’s no big deal,I don’t care
Inevitable wandering,people come and go
[TaeYang] I was born and I met you
And I have loved you to death
My cold heart that has been dyed blue
Even if you have left,I’m still here
[Daesung] Winter had passed
And the spring has come
We have withered
And our hearts are bruised from longing
[TaeYang] Again tonight,underneath that blue moonlight
I will probably fall asleep alone
Even in my dreams,I look for you
And wander around while singing this song
[G-Dragon] I’m singing my Blues~
[Seungri] Used to the blue tears,blue sorrow
[G-Dragon] I’m singing my Blues~
[Seungri] The love that I have sent away with the floating clouds
[G-Dragon] I’m singing my Blues~
[Seungri] Used to the blue tears,blue sorrow
[G-Dragon] I’m singing my Blues~
[Seungri] The love that I have sent away with the floating clouds Oh,Oh
