"I swear" 是 Fall Out Boy 的一首歌，其歌詞如下：
I swear I'm not lying
I swear I'm feeling
I swear I'm feeling everything
I swear I'm feeling everything
I swear I'm broken
But I swear my heart's still beating
It's like a 4 a.m. fantasy
You wake up feeling safe in the knowledge that
Somehow you'll be fine
Cause I'm in too deep, and I'm swimming against the current
And I swear my eyes will dry before my tears stop flowing
I don't want to fall asleep
Cause I know what I'll see
It's just a dream but it feels too real
I don't want to be alone anymore
Cause you were never really alone, oh oh oh oh oh oh oh oh oh
Chorus: (I swear)
And I don't want to be afraid anymore
I swear I can feel you pulling at my heart string now, yeah yeah yeah yeah yeah
(You never really) You never really were alone, oh oh oh oh oh oh oh oh oh
Verse 2: (Maybe it's the end of the world)
Maybe it's just the end of me and you
But I swear my heart will keep on beating, yeah yeah yeah yeah yeah yeah
You and me both got broken pieces missing of our heart from a lost connection (x2)
You can find comfort in each other when it's cold outside (find each other) (x3)
(I know that I was only here to catch your breath)
(Now it's time to let you go and let you feel) (x4)
Chorus: (I swear) (x3)
Bridge: (Cause when it's over and you're feeling down) (down) (x2)
Just remember what I said before and tell your girl, don't cry, you got someone to rely on (rely on) (x3) 歌詞講述了一段關係破裂後，男主女的互相鼓勵、互相關心。整個歌曲傳遞了男女互相鼓勵的信息。最後女生提醒不要輕易放棄關係，希望女生堅強，男生也表示相信女生可以依靠自己。總的來說，這首歌表達了愛情中的痛苦和掙扎，同時也傳遞了互相鼓勵和支持的信息。
