《Blue》是BigBang演唱的歌曲，發行於2013年，歌詞全文如下：
(Verse 1)
Seems like only yesterday
When we were in love
You and me
With no one else but each other
(Chorus)
But now we're far apart
Can't you see
The blue in our sky
Baby please don't go
I need you back here with me
(Verse 2)
All I ever wanted was to make you my own
I guess we both know it didn't work out
I miss your touch
The sound of your voice
You make everything brighter than blue
(Chorus)
But now we're far apart
Can't you see
The blue in our sky
Baby please don't go
I need you back here with me
(Bridge)
I'm sorry for all the times I was untrue
Now I'm wishing you were here with me
Blue, it's a beautiful day outside
But I'm all alone without you by my side
(Chorus)
But now we're far apart
Can't you see
The blue in our sky
Baby please don't go
I need you back here with me
Oh, I miss you so much baby girl
(Outro)
Baby girl, I hope you understand
That I miss you so much and I hope you can come back to me. BigBang《Blue》的歌詞表達了他們對於分手的痛苦和對於曾經愛情的懷念。他們希望對方能夠回到自己身邊，重新開始他們的愛情。這首歌也表達了他們對於愛情的執著和對於未來的期待。
