In an exclusive interview with Digital Spy, George Ergatoudis said that he has research to show music fans are bored of the "formulaic" mainstream.

"I am confident that we are in a year of transition and I fully expect guitar-based acts to start rising in popularity again," Ergatoudis told DS.
"The public is beginning to tire of the formulaic sounds that make up much of the Top 40 singles chart and we have audience research to back this up.
"They want more variety and that's good news for Radio 1. Having said that I don't think we'll see the important guitar acts of this decade really smashing it until 2015."
The BBC's Sound of 2013 longlist - which Ergatoudis votes on - featured seven guitar-based acts, including the hotly-tipped Palma Violets, Peace, Savages, Little Green Cars, Kodaline, King Krule and eventual winners Haim.

> Foals interview: 'Guitar rock revival is bulls**t'
However, Foals frontman Yannis Philippakis attacked the supposed re-emergence of indie/rock in an interview with DS last month, saying that guitar bands will never die and that what is fashionable is controlled by the media.
"I think [this guitar rock resurgence] is bulls**t. If drum 'n' bass won't die then guitar bands ain't going nowhere. It's just something that people say to try and add interest to what is essentially a very pedestrian thing to talk about," he said.
"Nothing really changes; you've just got slight vacillations of progress in music. There's always going to be guitar bands; it's whether some programmer or media hobnob in West London decides to say whether it's in or not.
"It's just to do with the transparency of it rather than how exciting it is. Often the most exciting moments in guitar music are when there's no attention on it. When people say, 'It's the reign of the guitar band', that's when the worst records get put out."
