By the Way is the eighth studio album by American rock band Red Hot Chili Peppers, released July 9, 2002, on Warner Bros. Records. It sold more than 286,000 copies in its first week, and peaked at number two on the Billboard 200. Singles included "By the Way," "The Zephyr Song," "Can't Stop," "Dosed" and "Universally Speaking". The lyrical subject matter vocalist Anthony Kiedis addresses in By the Way is a divergence from previous Red Hot Chili Peppers albums, with Kiedis taking a more candid and reflective approach to his lyrics.
 
By the Way was lauded by critics as a departure from the band's previous styles, and is recognized for the melodic and subdued emotions given by the Chili Peppers. Guitarist John Frusciante is credited with writing most of the album's melodies, backing vocal arrangements, bass lines and guitar progressions, therefore changing the direction of the recording dramatically: "his warm, understated guitar work and his doo-wop style vocal harmonies are king this time around." By the Way contained very little of the signature punk-funk fusion the band had become known for playing. Frusciante has stated that writing "By the Way [was] one of the happiest times in my life." The album went on to sell more than eight million copies worldwide.
 
By the Way was released on CD and LP on July 9, 2002, under the Warner Bros. label, selling 281,948 copies in the United States in its first week and 1.8 million worldwide. It was certified gold just a few months later on October 26, 2002. Five singles were released from the album; of these, the title track was the most successful, peaking at No. 2 on the UK charts and No. 1 on the Billboard rock charts. Although the album sold fewer copies than Californication, By the Way managed to peak at No. 2 on the Billboard 200, one spot higher than Californication. Around the world, the album debuted at number one in the UK, Switzerland, New Zealand, Austria, and Sweden; and number two in France. In March 2006, all Red Hot Chili Peppers' albums were made available for download from the iTunes Music Store and other online retailers.
