5 Seconds of Summer have been named the most talked about iTunes Festival artist.

The Australians were one of many acts who played the month-long run of gigs at London's Roundhouse in September.

According to a new study from SocialBro, the band had the biggest buzz on Twitter when it came to iTunes Festival slots.

The most retweeted tweet from the month was 5 Seconds of Summer talking about heading on stage.

40,000 tweets were apparently sent before the 'She Looks So Perfect' stars started their set.

Ed Sheeran and Jessie J were second and third on the list, whilst Maroon 5 and David Guetta completed the top five.
