歌詞如下：
You know I'm no good
I'm a bad influence on you
And you know I'm no good
But you still want more of me
I'm a fool, I'm a liar
I'm a bad, bad, bad, bad boy
But you still want more of me
You know I'm no good for your soul
But you still want more of me
You know I'm no good
But you love me still
You know I'm a cheat and a liar
And I don't care what they say
I don't care who I hurt or why
It's alright, it's alright with you
I'm a problem, I'm confused
I'm a bad, bad, bad, bad boy
But you still want more of me
You know I'm no good for your soul
But you still want more of me
You know I'm no good, no good, no good for me
So why can't we just lay our cards on the table now?
So why can't we just stop this dance and call it a day?
'Cause I know I'm no good, no good, no good for me. No good. No good. No good. No good. No good. No good. No good. No good. No good. No good. No good. No good. No good. No good. No good. No good.
