The reception of "1" surpassed all critical and commercial expectations. It reached number 1 in over 35 countries, achieving the record for the album debuting at the top of the most national charts ever. It became the highest-selling of 2000 and, some time later, of the entire decade. This achievement made the Beatles the first and only artist to have the best-selling albums of two different decades: they also released the best-selling album of the 1960s, "Sgt. Pepper's Lonely Hearts Club Band". No tracks from "Sgt. Pepper" appear on this album. With this album, the Beatles also achieved having an album hit the number 1 position in the US in four non-consecutive decades (1960s, 1970s, 1990s and 2000s).
