Task: Question Generation
Input (English): Passage: In Rainbows was downloaded an estimated 1.2 million times on the day of release, but Radiohead's management did not release sales figures, claiming that the distribution was intended to boost later retail sales. Colin Greenwood explained the internet release as a way of avoiding the "regulated playlists" and "straitened formats" of radio and TV, ensuring fans around the world could all experience the music at the same time, and preventing leaks in advance of a physical release. O'Brien said the self-release strategy sold fewer records, but made more money for the band as there was no middleman. A special "discbox" edition of In Rainbows, containing the record on vinyl, a book of artwork, and a CD of extra songs, was also sold from Radiohead's website and shipped in late 2007.The retail version of In Rainbows was released in the UK in late December 2007 on XL Recordings and in North America in January 2008 on TBD Records, charting at number one both in the UK and in the US. The success – after having been legally available for months as a free download – was Radiohead's highest chart success in the US since Kid A. It became their fifth UK number-one album and sold more than three million copies in one year. The album received acclaim for its more accessible sound and personal lyrics. It was nominated for the Mercury Music Prize and won the 2009 Grammy awards for Best Alternative Music Album and Best Boxed or Special Limited Edition Package. It was nominated for five other Grammy awards, including Radiohead's third nomination for Album of the Year. Yorke and Jonny Greenwood performed "15 Step" with the University of Southern California Marching Band at the televised award show.
