Sunday Times journalist Lynn Barber takes over editorial control to 'curate' the second episode. Lynn wants to look at some of the most exciting developments in popular culture in 2015. She chats to Mark Ronson, the most intriguing pop star of the modern age, as well as looking at the boom of ingenious, inventive magazines bought by and made for young people. She sticks up for that supposed 'Mickey Mouse degree' - media studies - while former media studies student Jon Ronson explores the theme of shame in the internet age.
