How does my media product use, develop or challnge forms of conventions in real media product?

My completed Media Product does follow some of the conventions of a radio broadcast. The conventions that it follow's is that of the speed of how the stories are read and what stories are presented as well as how long they spend on each story. I also use a theme tune which also helps recognise the radio station or broadcast that my intended audience is listening to.
I had attempted to add some interesting sounds which are rarely used on broadcasts as well as adding A upbeat sound which helps the audience stay in tune.
