I have this rule: It's like, if you write an amazing, cool song that you mean and then you go put your leather pants on and sing it in front of people; that's OK. But if you put your leather pants on and stand in front of the mirror and go, "Ok, I've got to write a song to fit these pants," then you're in trouble.
I didn't even write the lyrics down. I got in the booth, I put down a little guitar riff and the idea I had was it was going to be really simple, I just want it to be all about the lyrics and I just literally sang the lyrics.
