Motown is an American record company.
 The record company was founded by Berry Gordy Jr. as Tamla Records on January 12, 1959, and was incorporated as Motown Record Corporation on April 14, 1960, in Detroit, Michigan.
 The name, a portmanteau of "motor" and "town", has also become a nickname for Detroit.
 Motown played an important role in the racial integration of popular music as an African American-owned record label that achieved significant crossover success.
 In the 1960s, Motown and its subsidiary labels (including Tamla Motown, the brand used outside the US) were the most successful proponents of what came to be known as the Motown Sound, a style of soul music with a distinct pop influence.
 During the 1960s, Motown achieved spectacular success for a small record company: 79 records in the Top Ten of the "Billboard" Hot 100 record chart between 1960 and 1969.
Renaissance (Tamla T-325L) was a critically acclaimed 1973 album by R&B group The Miracles on Motown Records' Tamla label, noted as the first-ever album by the group not to feature original lead singer Smokey Robinson on lead vocals.
 Instead, his replacement, new lead singer, Billy Griffin did the lead chores on this album.
Stevland Hardaway Morris (born Stevland Hardaway Judkins; May 13, 1950), known by his stage name Stevie Wonder, is an American musician, singer, songwriter, record producer, and multi-instrumentalist.
 A child prodigy, he is considered to be one of the most critically and commercially successful musical performers of the late 20th century.
 Wonder signed with Motown's Tamla label at the age of 11, and he continued performing and recording for Motown into the 2010s.
 He has been blind since shortly after birth.
"Bad Girl" is a 1959 doo-wop single by The Miracles.
 Issued locally on the Motown Records label, it was licensed to and issued nationally by Chess Records because the fledgling Motown Record Corporation did not, at that time, have national distribution.
 It was the first single released (and the only one released by this group) on the Motown label - all previous singles from the company (and all following ones from the group) were released on Motown's Tamla label.
 Although The Miracles had charted regionally and on the R&B charts with several earlier songs, including "Got a Job", "I Cry", "I Need a Change", and "(You Can) Depend on Me", "Bad Girl" was their first "national" chart hit, reaching #93 on the "Billboard" Hot 100.
 Written by Miracles lead singer Smokey Robinson and Motown Records' President and Founder Berry Gordy, "Bad Girl" is a sad, remorseful ballad about a young woman, whom Robinson, as the narrator, says "was so good at the start", but who later in the song "is breaking my heart".
 It is in the popular doo-wop style, as several of The Miracles' songs were during the late 1950s.
 The record's success, coupled with the distributor's failure to pay Gordy and The Miracles properly for its sales, prompted Robinson to urge Gordy to "go national" with it, meaning that Motown should do its own national distribution of its songs, and eliminate the middleman, to ensure that all money from sales of its records would go directly to the label.
"Buttered Popcorn" is a 1961 song written by Motown president Berry Gordy and songwriter Barney Ales, and produced by Gordy, and released as a Tamla label single by Motown singing group The Supremes.
 It was the group's second single since signing with Motown Records (and their third overall) as well as their second, and last, single for the Tamla label, before moving to the Motown label.
"My Cherie Amour" is a 1969 soul classic by Motown singer-songwriter Stevie Wonder.
My Cherie Amour is an album by American singer-songwriter Stevie Wonder released on the Tamla (Motown) label on August 29, 1969, his eleventh studio album.
 The album yielded a couple of major hits, including the title track and "Yester-Me, Yester-You, Yesterday", as well as Wonder's takes on the 1967 hit "Light My Fire" by The Doors and "Hello, Young Lovers" from "The King and I".
Robert Willie White (November 19, 1936 – October 27, 1994) was an African-American soul musician, one of the guitarists for Motown's in-house studio band, the Funk Brothers, White is best known for performing the guitar riff on The Temptations' number-one hit single "My Girl", but played the guitar on many successful Motown records, including "Can I Get a Witness" by Marvin Gaye, "You Keep Me Hangin' On" by The Supremes, "My Cherie Amour" by Stevie Wonder, "Something About You" by the Four Tops and "It's a Shame" by The Spinners.
"Yester-Me, Yester-You, Yesterday" is a 1969 soul song written by Ron Miller and Bryan Wells, released by American Motown singer-songwriter-musician Stevie Wonder on the album "My Cherie Amour".
 The song continued Wonder's success on the pop charts.
 It reached #7 on the pop singles chart and become Wonder's ninth Top 10 single of the 1960s.
 The single fared even better on the UK singles chart where it reached #2 in December 1969, and at that time, it was Wonder's biggest UK hit.
