James Masterton's Chart Update Podcast was first produced in January 2008 and has now been an online fixture for nine and a half years. Now appearing as a series of regular specials, each podcast sees James (and occasional guests) discuss the big news stories as they relate to the UK singles and albums charts. We look at the stories and sales behind the Number One single, acts who have achieved true greatness or simply peel back the layers of the most notable or controversial stories in music. This is the chart addicts' comprehensive audio guide to the stories the big music radio stations are just too busy to tell you.

iTunes reviewers are unanimous in their praise, describing the show as: "Factual and fascinating" "Essential listening" "Only wish it lasted longer"
