create an app that transfer playlist to an app and allow auto play for cars

if you can create this app for free i can give you 5% of the total app revenue create a car app that captures music from your playlist the goal behind this is to eliminate people in cars touching phones, so car accidents are eliminated, the way i want this app to work is for example a person get in there car, go to the app and it will pull up there playlist and after they pull up there playlist what ever music is on the phone they can say the artist name and the song and it will play instantly, for example if a person yell an artist name for example justin bieber what do you mean and the song automatically starts playing in the car, what that will do is ensure safety and stream whatever song someone wants
