Stephen Thomas Erlewine at AllMusic: Prince designed Purple Rain as the project that would make him a superstar, and, surprisingly, that is exactly what happened. Simultaneously more focused and ambitious than any of his previous records, Purple Rain finds Prince consolidating his funk and R&B roots while moving boldly into pop, rock, and heavy metal with nine superbly crafted songs. Even its best-known songs don't tread conventional territory: the bass-less "When Doves Cry" is an eerie, spare neo-psychedelic masterpiece; "Let's Go Crazy" is a furious blend of metallic guitars, Stonesy riffs, and a hard funk backbeat; the anthemic title track is a majestic ballad filled with brilliant guitar flourishes. Although Prince's songwriting is at a peak, the presence of the Revolution pulls the music into sharper focus, giving it a tougher, more aggressive edge. And, with the guidance of Wendy and Lisa, Prince pushed heavily into psychedelia, adding swirling strings to the dreamy "Take Me With U" and the hard rock of "Baby I'm a Star." Even with all of his new, but uncompromising, forays into pop, Prince hasn't abandoned funk, and the robotic jam of "Computer Blue" and the menacing grind of "Darling Nikki" are among his finest songs. Taken together, all of the stylistic experiments add up to a stunning statement of purpose that remains one of the most exciting rock & roll albums ever recorded.

Wiki: Purple Rain is the sixth studio album by American recording artist Prince, released on June 25, 1984 by Warner Bros. Records. It is the first to feature the billing of his band the Revolution, and is the soundtrack to the 1984 film of the same name. Purple Rain was musically denser than Prince's previous albums, emphasizing full band performances, and multiple layers of guitars, keyboards, electronic synthesizer effects, drum machines, and other instruments.

As a soundtrack record, much of the album had a grandiose, synthesized, and psychedelic sheen to the production and performances. The music on Purple Rain is generally regarded as the most pop-oriented of Prince's career, though a number of elements point towards the more experimental records Prince would release after Purple Rain. The music video for the album's lead single "When Doves Cry" sparked controversy among network executives, who thought that its sexual nature was too explicit for television. The risqué lyrics of "Darling Nikki" raised complaints from Tipper Gore and the Parents Music Resource Center and contributed to the implementation of Parental Advisory stickers and imprints on album covers.

Purple Rain became Prince's first album to reach number one on the Billboard 200. The album spent 24 consecutive weeks atop on the Billboard 200 and was present on the chart for a total of 122 weeks. "When Doves Cry" and "Let's Go Crazy" reached number one the Billboard Hot 100, while "Purple Rain" peaked at number two and "I Would Die 4 U" peaked at number eight. In May 1996, the album was certified 13x Platinum by the Recording Industry Association of America (RIAA). Its total sales stand at 25 million copies worldwide, making it one of the best-selling albums of all time. Prince and the Revolution won Grammy Awards for Best Rock Vocal Performance by a Duo or Group with Vocal and Best Score Soundtrack for Visual Media, while Prince also won the Academy Award for Best Original Song Score for the film Purple Rain.

In addition to Purple Rain's breakthrough sales, music critics noted the innovative and experimental aspects of the soundtrack's music, most famously on the spare, bass-less "When Doves Cry". Other aspects of the music, especially its synthesis of electronic elements with organic instrumentation and full-band performances along with its consolidation of rock and R&B, were identified by critics as distinguishing, even experimental factors. Purple Rain is regularly ranked among the greatest albums of all time. It was inducted into the Grammy Hall of Fame and added to the Library of Congress' National Recording Registry list of sound recordings that "are culturally, historically, or aesthetically important".
