The Vodafone Big Top 40 Show
Sun 22nd Apr at 4pm
Marvin Humes plays the nation's Top 40 songs, based on real-time iTunes sales. We lockdown the Top 10 during the show at 6pm. The rest of the chart, numbers 11 to 40, are a mix of iTunes sales data from across the week and airplay data from the stations which the show is broadcast on around the UK.
