Two bosses from BBC Radio 1 have been discussing how they reach their decisions on which tunes will make the station’s playlist.

Head of music George Ergatoudis and music policy director Nigel Harding spoke to Music Week about some of their recent choices involving tracks by the likes of Green Day, Robbie Williams, Muse and Noel Gallagher.

Although Robbie Williams’ 2012 solo single ‘Candy’ did not make the cut, the Take That’s star’s recent collaboration with Dizzee Rascal ‘Goin' Crazy’ did.

When quizzed about this ruling, Harding explained: “This is all about the age of the artist's primary audience. In Robbie's case we believe that his main fan base is comfortably over the age of 30, whereas Dizzee's is clearly much lower.”

Two other artists who failed to make it onto the Radio 1 airwaves recently are Green Day and Noel Gallagher.

Harding argued: “I think Noel's music feels more at home on Radio 2 and the last Green Day project [‘Uno! Dos! Tre!’] simply wasn't good enough.”

A further act who’s future on Radio 1 may be in jeopardy are Muse, as Harding asserted:

"Muse are approaching a crossroads - their last single [‘Panic Station’] was the first one not playlisted by Radio 1 in a decade. The door remains open to them but we'll have to think carefully about their next album."
