"The record labels have devised a lobbying strategy that relies on cherry-picking international examples that paint a distorted picture of copyright law," NAB spokesman Dennis Wharton said in a press release. "The U.S. protects sound recordings for 45 years longer than Canada and many countries in Europe and elsewhere; if it's 'international parity' that RIAA is looking for, they ought to examine the entire landscape," he said. NAB's analysis also points out that other countries' broadcasting systems are or were government-subsidized while the U.S. business was built by private commercial entrepreneurs.

But the MusicFirst coalition, which supports the legislation, bit back by claiming the analysis is suspect and stale. According to the coalition, the NAB's Canadian counterpart submitted the same study to support its claim that radio play promotes album sales in a proceeding before the Copyright Board of Canada. In November 2008, the board threw it out because the underlying data was destroyed. The same analysis was released by NAB last June and again Monday, officials said. Wharton scoffed at the notion that NAB destroyed data and added: "MusicFirst should get its facts straight before making unfounded allegations."
