Ultimately her song failed in this. Watching the episode, it's amusing to see her take on modern female empowerment. Her lyrics were not club-worthy, as Britney Spears and Rihanna would never speak of rubbing a man's feet or cooking a meal for them, as was suggested in her writing session. If you listen where club music is today, you can see the difference in what this group wrote, and what is working on radio, which takes a much more aggressive female stand. Consider the first verse of Britney's "Till the World Ends":
This kitten got your tongue tied in knots I see
Spit it out 'cause I'm dying for company
I notice that you got it
You notice that I want it
You know that I can take it to the next level baby!
If you want this good b---h
Sicker than the remix
Baby let me blow your mind tonight
Sadly no one else in her group was able to really lyrically embody the girl power, modern seductress we were looking for, and the song became generic and weak, landing them in the bottom.
Brian took a risk with his low chorus, but allowed it to be strayed from when they formed a team. Co-writing is awkward, as no one wants to be bossy, yet if you feel strongly you have a winning idea, you owe it a fight. The girls did not seem to grasp how hooky a male low vocal was like that. I could have heard Enrique Iglesias or Pitbull doing something like that. A low chorus was memorable, a girl singing it suddenly made the melody less hooky -- and suddenly the cool tag line "Be my ridiculous" blended in to the background. One of the most important things about co-writing is having the self-awareness to recognize a good idea, whether it is yours or someone else's. There can be no ego in the room -- only a tenacious determination to make that song the best at any cost -- be it ruffling feathers with someone who doesn't agree or seeing someone else has a better idea. Brian had obviously listened to the radio, and knew a low chorus would stand amongst the pack out for a dance song. The girls both admitted they had no experience with dance, but yet they didn't follow Brian's lead and had out of touch opinions about how to tackle the chorus -- and it showed.
