Billboard R&B Number-One Albums, 1985 to 2004 Quiz

Every album to finish a year at number one on Billboard's R&B/hip-hop year-end chart between 1985 to 2004: 20 years, one per year, taken from the same published table as the complete run. This is the era cut, for when the full set from 1966 is more than you want in one sitting. Name each from its year, pick the year's real number one from a group of genuine chart-toppers, match each album to the artist credited with it, snap each censored cover to its album title, sort a selection into the order they led, or tap the era's number ones out of a grid seeded with real number ones of the same chart from other eras. Parsed verbatim from the published year-end table; no answer is named here.
