Chris & Scott want to keep the whole car happy on the school run.
Every afternoon, they play an old throwback song and a new song for a child and their parent or guardian who are on their way to school.
It's really easy to take part too. All you need to do is download the Radio Essex app from wherever you get apps for your phone from.
In the top right corner, click the speech bubble and send them an old school track and a new school track during the Big Drive Home.
Listen in each afternoon at 3pm and you might hear your songs playing across the county!
