It's the most popular programme on Radio 4 by far, the flagship Radio 4 news programme, which begins the day for more than seven million listeners. No programme attracts more correspondence from Feedback listeners than Today.

This week Feedback puts some of that correspondence to Jamie Angus, who's been Editor of the programme for almost nine months. In his first radio interview, Jamie deals with listener complaints including an interview in which presenter Evan Davis continually interrupted politician Iain Duncan Smith, a Today item with the victim of an acid attack, and the question of balance on climate change. He also sets out his vision for Today.

The BBC iPlayer App is a popular device for radio listeners wanting to 'tune in' on the move, via their tablets and phones. But recent changes to the way it works have left many Feedback listeners unhappy. One of them is Nick Gilbody. He took up Feedback's invitation to come to London and meet Roger Bolton, as well as the man responsible for making sure the app is coming up to scratch, Andrew Scott, General Manager of Radio - BBC Future Media. But does the encounter solve his problems, and leave him a satisfied Feedback customer?

We'll also be travelling to Emmanuel Church in Didsbury near Manchester, to meet the team who produce the world's longest-running daily non-news radio show. The Daily Service has brought Christian worship to BBC listeners since 1928. We hear from the singers, the presenter and producer who decide on the themes for worship, and the music at the programme's heart.
