《Bad Days》的歌詞如下：
VERSE 1
Everybody's got a little thing they call a bad day
Just another day, just another test, to see how you react
PRE-CHORUS
But when the night falls and the stars start to shine
You'll be feeling better, I can tell
CHORUS
So don't let them get you down, you'll be alright
It's just a bad day, it's not a sign of anything wrong
It's just a bad day, it's not a big deal
You'll be laughing tomorrow, when the sun comes up again
VERSE 2
Everybody goes through some kind of struggle
It's just a matter of time, before you rise up again
PRE-CHORUS
But when the sun sets and the moon starts to shine
You'll be feeling stronger, I can tell
CHORUS
So don't let them get you down, you'll be alright
It's just a bad day, it's not a sign of anything wrong
It's just a bad day, it's not a big deal
You'll be laughing tomorrow, when the sun comes up again
BRIDGE
You're feeling low, you're feeling down, but it won't last
The sun will come up tomorrow, it always does
CHORUS x2
So don't let them get you down, you'll be alright
It's just a bad day, so don't let it bring you down tonight
It's not the end of the world, it's not the end of your dreams
You'll be laughing tomorrow, when the sun comes up again
