What is the secret of making children's radio - which children actually want to listen to?

As listeners young and old object to the loss of much of BBC children's on-air programming, Roger Bolton asks Paul Smith, Head of Editorial Standards for BBC Audio & Music, if the BBC has given up trying to find an answer. Gregory Watson, Managing Director of children's station Fun Kids and Susan Stranks of the National Campaign for Children's Radio add their views to the debate.

Does BBC 6 Music really offer an alternative to more mainstream stations? If so, why is it playing so much Coldplay? Bob Shennan, controller of 6 Music, defends the playlist.

And listeners have been concocting fake Radio 4 programmes on Twitter. Apparently Feedback is 30 minutes of unbearable noise.

Contact the Feedback team to let Roger know what you'd like him to tackle this series about anything you've heard on BBC radio.

Producer: Karen Pirie A Whistledown production for BBC Radio 4.
