《Bad Day》是歌曲，而不是一個特定的人唱的。以下是《Bad Day》的歌詞：
Verse 1:
I woke up this morning feeling like a jerk
Didn't even like my face in the mirror
And I don't know why, it won't go away
A headache's brewing and it won't take a day off
Chorus:
This is definitely gonna be a bad day
Gonna feel like a punching bag on a roller coaster day
Oh oh oh
Just gotta roll with the punches, and try to get through it
Gonna be alright, just gotta laugh it off, it's gonna be a bad day
Verse 2:
I'm late for work, I'm running out of time
Got a million things to do and I'm running out of chances
And I don't know why, it won't go away
But I'm gonna try and make it through today
Bridge:
Sometimes life just doesn't go your way
But you can't let it bring you down
You gotta keep on going, keep on trying
Gonna make it through the day, gonna make it through the night
Chorus:
This is definitely gonna be a bad day
Gonna feel like a punching bag on a roller coaster day
Oh oh oh
Just gotta roll with the punches, and try to get through it
Gonna be alright, just gotta laugh it off, it's gonna be a bad day
Outro:
Just gotta laugh it off, roll with the punches, and get through it, gonna be alright.
