Download: Architects talk headlining and cake with Metallica

A lot has changed since Download Festival first launched in 2004.
But many of the headliners at the UK's biggest rock and metal festival have stayed the same - until this year.
Bring Me the Horizon and Architects are closing Friday's main stage - the first time both British bands have had top billing at Donington.
"It'll be a beautiful moment for the UK scene," Architects frontman Sam Carter tells BBC Newsbeat.
"When I think about where both our bands have come from to where we are now it's absolutely staggering."
Architects, from Brighton, and Bring Me the Horizon, from Sheffield, have slowly worked their way up the rock ladder, gathering new fans along the way.
Neither had headlined Download before, which traditionally opts for "legacy acts" - older bands seen as guaranteed ticket-sellers.
But some fans have long been calling for new artists to be given a chance.
Friends Jordan, 24, Alistair, 25, and Chloe, 21, told Newsbeat they'd come to this year's Download to see both UK acts.
