The LP (Long Play), or long-playing microgroove record, is a format for phonograph (gramophone) records, an analog sound storage medium. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire record industry. Apart from relatively minor refinements and the important later addition of stereophonic sound capability, it has remained the standard format for vinyl "albums" up to the present.

At the time the LP was introduced, nearly all phonograph records for home use were made of an abrasive (and therefore noisy) shellac compound, employed a much larger groove, and played at approximately 78 rpm, limiting the playing time of a 12-inch record to less than five minutes per side. The new product was a 12 or 10-inch fine-grooved disc made of vinyl and played with a smaller-tipped "microgroove" stylus at a speed of 33⅓ rpm. Each side of a 12-inch LP could play for more than 20 minutes. Only the microgroove standard was truly new, as both vinyl and the 33⅓ rpm speed had been used for special purposes for many years, as well as in one unsuccessful earlier attempt to introduce a long-playing record for home use. Although the LP was especially suited to classical music because of its extended continuous playing time, it also allowed a collection of ten or more typical "pop" music recordings to be put on a single disc. Previously, such collections, as well as longer classical music broken up into several parts, had been sold as sets of 78 rpm records in a specially imprinted "record album" consisting of individual record sleeves bound together in book form. The use of the word "album" persisted for the one-disc LP equivalent.

An album may be understood as a collection of recordings, released as a single package on gramophone record, cassette, compact disc, or via digital distribution, however the concept is found in printed music dating into the early nineteenth century in works by composers such as Schumann and Mendelssohn. The word derives from the Latin word for list.

Today, with the vinyl record no longer being used as the primary form of distribution, the term "album" can still be applied to any sound recording collection, such as those on compact disc, MiniDisc, Compact audio cassette, and digital or MP3 albums.Cover art is also considered an integral part of the album. Many albums also come with liner notes and inserts giving background information or analysis of the recording, reprinted lyrics, images of the performers, or additional artwork and text. These are now often found in the form of CD booklets.

Vinyl LP records have two sides, each comprising one half of the album. If a pop or rock album contained tracks released separately as commercial singles, these were often traditionally placed in particular positions on the album. A common configuration was to have the album led off by the second and third singles, followed by a ballad. The first single would lead off side 2. In the past many singles (such as the Beatles' "Hey Jude" and Bob Dylan's "Positively 4th Street") did not appear on albums, but others (such as the Beatles' "Come Together" and Dylan's "Like a Rolling Stone") were part of an album released concurrently. Today, many commercial albums of music tracks feature one or more singles, which are released separately to radio, TV or the Internet as a way of promoting the album. Albums have also been issued that are compilations of older tracks not originally released together, such as singles not originally found on albums, b-sides of singles, or unfinished "demo" recordings.

Marvin Pentz Gay, Jr. (April 2, 1939 – April 1, 1984), better known by his stage name Marvin Gaye (he added the 'e' as a young man), was an acclaimed American singer-songwriter and musician with a three-octave vocal range, who achieved major success in the 1960s and 1970s as an artist for the Motown Records label. He was shot dead by his father on April 1, 1984.

Starting his career as a member of the doo-wop group The Moonglows in the late 1950s, he ventured into a solo career after the group disbanded in 1960, signing with Motown Records subsidiary, Tamla. He started off as a session drummer, but later ranked as the label's top-selling solo artist during the 1960s. He was crowned "The Prince of Motown" and "The Prince of Soul". because of solo hits such as "How Sweet It Is (To Be Loved by You)", "Ain't That Peculiar", "I Heard It Through the Grapevine," and his duet singles with singers such as Mary Wells and Tammi Terrell.

His work in the early- and mid-1970s included the albums, What's Going On, Let's Get It On, and I Want You, which helped influence the quiet storm, urban adult contemporary, and slow jam genres. After a self-imposed European exile in the early 1980s, Gaye returned on the 1982 Grammy-Award winning hit, "Sexual Healing" and the Midnight Love album before his death.
