Def Leppard have announced plans to re-record their entire back catalogue because of an ongoing royalty dispute with their label of 30 years, Universal Music Group. Its more bad news for UMG who are seeking EU ad US regulatory approval to swallow up EMI's recorded music division enabling the new group to control almost 50% of the global recorded music market. Along with the ongoing claim from Eminen producers FBT over digital royalties, Def Leppard frontman Joe Elliott told Billboard that the English band were "at loggerheads" with Universal over royalty payments, especially compensation for digital downloads. "We just sent them a letter saying: 'No matter what you want, you are going to get "no" as an answer, so don't ask," adding "That's the way we've left it. We'll just replace our back catalogue with brand new, exact same versions of what we did."
