Maev Kennedy of The Guardian described the programme as "a broadcasting phenomenon", while Tim Davie, head of music and audio at BBC radio, commented that "the results have been nothing short of stunning", exceeding the BBC's wildest hopes for the programme. At the time of the writing of Kennedy's article, just before the start of the last week of the series, the radio broadcasts regularly had up to four million listeners, while the podcast downloads had totalled 10,441,884. Of these, just over half, 5.7 million, were from the UK.
