The lyrics of OK Computer paint a panorama of a dystopian world, marked by excessive consumerism, social disconnection, technological anxiety, and political corruption. These themes intertwine with reflections on transportation, conformity, paranoia, death, and modern life in a globalized Britain, offering a vision that many consider prescient of the 21st century. Despite low expectations from their record label, which considered it uncommercial, the album climbed to the top spot on the UK albums chart and debuted at number 21 on the Billboard 200, marking Radiohead's highest entry on the US charts up to that point. Songs like "Paranoid Android", "Karma Police", "Lucky", and "No Surprises" became singles that helped expand their international popularity.
The impact of OK Computer was immediate and lasting. It was critically acclaimed, considered one of the most important albums of the 90s and of all time. It received a nomination for Album of the Year and won the award for Best Alternative Music Album at the 1998 Grammy Awards, in addition to a nomination for Best British Album at the Brit Awards that same year. This record marked a turning point in British rock, driving a shift from Britpop towards a more melancholic and atmospheric alternative sound, which would define the following decade. In 2014, the Library of Congress of the United States added it to the National Recording Registry for its cultural, historical, and aesthetic significance. The song "Lucky", recorded in 1995 for a charity album, was fundamental in defining the sound and atmosphere the band sought for this new work.
