Brooks wrote this with Shelly Peiken, who later co-wrote Christina Aguilera's "What A Girl Wants," but had yet to write a hit. She told the story in a Songfacts interview
"Meredith Brooks had a development deal on Interscope Records. She was writing and turning in songs to them and they kept dismissing her songs. I think she had one more song left and if they passed on it she would have to leave. She was introduced to me by her manager and I went to see her play at a club in Hollywood. I thought she had balls. I thought she could really sing. But I didn't know what to write with her. Then I had this really miserable day and I started writing a song with the line, 'I hate the world today.' I thought, Oh my God, I'm gonna call that girl Meredith because she needed a song to bring to Interscope
So I called her the morning after I had this idea and she loved it. She came over and we wrote it together start to finish. She picked up an acoustic guitar and honestly, it was just line, line, line, line. It was like ping pong. It was really wonderful. That's the way it's supposed to be: Somebody says a line and it makes you think of another line. When we were done, we were excited, but I never like to get my hopes up because this business is full of disappointments.
She made a demo and took the song to Interscope and they passed! Her manager got in the car and went over to Capitol and Capitol signed her that day. She called me and she said, 'They're gonna release this as a single.' And I thought, 'No way.'
I had been writing songs that were recorded as album cuts for 10 years without ever having a song on the radio in my country. When I first heard it, I was riding down a hill in Laurel Canyon in my tiny little Miata. I had a huge pregnant belly up against the wheel and I was listening to K-ROQ and I heard, 'I hate the world today' and I nearly peed in my pants."
When "Bitch" took off, Interscope signed Brooks. She and Peiken wrote six more songs that were included on the Blurring The Edges
album, which sold over a million copies. This was enough to buy Peiken a house with her own studio.
