Urban contemporary music in the context of "Urban adult contemporary"

Contemporary hit radio (CHR, also known as contemporary hits, hit list, current hits, hit music, top 40, or pop radio) is a radio format common in many countries that focuses on playing current and recurrent popular music as determined by the Top 40 music charts. There are several subcategories, dominantly focusing on rock, pop, or urban music. Used alone, CHR most often refers to the CHR-pop format. The term contemporary hit radio was coined in the early 1980s by Radio & Records magazine to designate Top 40 stations which continued to play hits from all musical genres as pop music splintered into adult contemporary, urban contemporary, contemporary Christian and other formats.

The term "top 40" is also used to refer to the actual list of hit songs, and, by extension, to refer to pop music in general. The term has also been modified to describe top 50; top 30; top 20; top 10; hot 100 (each with its number of songs) and hot hits radio formats, but carrying more or less the same meaning and having the same creative point of origin with Todd Storz as further refined by Gordon McLendon as well as Bill Drake. The format became especially popular in the mid-sixties as radio stations constrained disc jockeys to numbered play lists in the wake of the payola scandal.

Christian hip-hop (originally gospel rap, also known as Christian rap, gospel hip-hop or holy hip-hop) is a cross-genre of contemporary Christian music and hip-hop. It emerged from urban contemporary music and Christian media in the United States during the 1980s.

Christian hip-hop music first emerged on record in 1982 with a track entitled "Jesus Christ (The Gospel Beat)" by Queens, New York artist McSweet. The first full-length Christian hip-hop album, Bible Break, by Oklahoma artist Stephen Wiley, was released in 1985, with the title track becoming a hit on Christian radio in 1986. Other early Christian hip recording artists from the mid-1980s included P.I.D. (Preachas in Disguise), who recorded to funky rock rhythms, as well as JC & the Boys and Michael Peace. During the 1990s and 2000s, rapper KJ-52 rose to prominence in the field.
