《一天一天》是BIGBANG演唱的歌曲，收錄於專輯《Alive》中。
中文歌詞：
一天一天活下去 就算很痛也想要過日子
因為害怕所以顫抖 顫抖的時候閉上眼睛
在腦海里描繪的你的樣子 連起來像條長街
不管在哪裡 不管何時 都會來到我身邊
像夢一樣 無法相信 我的心就像漂浮著
像天空一樣 我的心也變得晴朗
一天一天活下去 就算很痛也想要過日子
你給我的傷痕 就算想忘記也忘不掉
但這是證據 證明我愛過你的證據
想要對你微笑說些話語 不知何時變得這樣需要你
我該不該從記憶中抹去你 我猶豫不決
想要一天一天活下去 就算很痛也想要過日子
不管何時何地都會想起你 我所剩下的只有你
在黃昏時 慢慢漂浮的雲彩
就像那天一樣 在黃昏時分想起你的我
韓文歌詞：
Live one day even if it hurts I want to live just for today
I'm trembling because I'm afraid If I close my eyes, will you disappear?
The image of you that flashes in my mind Is like a long street that connects us.
Wherever whenever you will come to me like a dream I can't believe my heart is floating just like the sky.
My heart becomes clear like the sky Live one day even if it hurts I want to live just for today.
The scars that you left on me I can't forget them even if I try But they are a witness Witnesses to the love that I once had for you.
I want to smile at you and say something But I'm so dependent on you I don't know when I became like this. Should I try to erase you from my memories? I'm hesitant. Live one day even if it hurts I want to live just for today.
You are the only thing left in my life Whenever and wherever I feel lonely, you are there. Like a cloud floating in the dusk just like that, like a cloud floating in the dusk, missing you at that time.
