Download festival's director, John Probyn, has asked the official website's users not to blame him for this year's line-up.
KISS, The Offspring and Lost Prophets are set to headline the festival, which kicks off tomorrow morning (Friday 13 June) at Donington Park, in Leicestershire, and will run through until Sunday (15 June).
But regulars of the rock and metal event have been using Internet messageboards to voice their opinions on this year's line-up, which includes controversial acts such as grime star Lethal Bizzle and indie bands Ash and The Subways.
While some have praised Download for widening its scope, others have accused the festival of betraying its roots.
Speaking at the traditional 'Boardies' party, which took place earlier this afternoon (12 June), Probyn said: "Before I start I'd like to say the line-up had nothing to do with me," which received a loud cheer from the crowd.
They remained in excitable spirits after his introduction, though, with fans sticking around to check out Essex rockers Forever Never.
Organisers have also changed the layout of the site with all three main stages now outside of the Donington Park racetrack. The main stage is now nestled in a natural amphitheatre, while the second stage will be an open-air arena for the first time ever.
Thousands arrived early to soak up the atmosphere and stake their places in the campsite, with a fairground and silent disco set to run through until the early hours.
