Longtime Radiohead producer (and Thom Yorke's Atoms For Peace bandmate) Nigel Godrich has taken to Twitter to express his disgust at a new report on digital filesharing published by the London School Of Economics.

The paper, which will be sent to British MPs, has looked at new revenue streams for musicians and labels (concerts etc.) and concludes that "revenues have not declined as dramatically has been suggested."

In reaction, Godrich tweeted Kerry McCarthy MP: "@KerryMP Totally distraught by this… http://www.scribd.com/doc/172985274/..."

The OK Computer producer then went on to outline his argument:

"The recorded music industry has been so decimated by piracy that the only way for artists to survive is by gaining visibility at any cost, which includes allowing piracy itself, or virtual piracy like subscription streaming services, and earning from other means like merchandise or concert tickets, none of which are 'content'.

"That is not an argument for relaxing copyright law! T-shirts and tickets are nothing to do with 'copyright and creation', which is the supposed subject of this document. I hope the government sees how ridiculous this document seems to people who make records. The authors are 'pro piracy' and they wish to influence the UK government's upcoming review of digital copyright law. It's madness."

The LSE briefing paper states:

"We show that new business models are enabling the industry to gain advantage by building on a digital culture based on sharing and co-creating," it reads. "Taking total revenues of the music industry into account - i.e. including revenues from concerts and publishing rights, these revenues have not declined as dramatically has been suggested; they have increased considerably from 1998 to the 2000s.

"These revenues have stagnated in the last few years, but the claims of many in the music industry about a dramatic decline in revenue apply specifically to the sale of CDs and vinyl. As Figure 1 shows, overall revenue of the industry in 2011 was almost USD 60 bn, and revenues from live performances and publishing rights largely offset the revenue decline associated with sales of CDs and vinyl."

Godrich and Thom Yorke has both recently been outspoken about streaming services, with Yorke removing their music from Spotify. Godrich's latest comments come as Spotify celebrates its fifth birthday by striking up a promotional partnership with the BBC, which will see the British national broadcaster encouraging their radio listeners to create playlists on the service.
