At one time the R&B charts were referred to as "race records" and for a time in the '80s "Hot Black Singles", which sounds like an African-American themed dating or sex site.
So looking what I think is a selection of hits from those two eras Herb Alpert (who's actually Jewish it seems), Anita Baker, Bell Biv DeVoe, Bobby Brown, Natalie Cole, Roberta Flack, Aretha Franklin, Marvin Gaye, John Lee Hooker, Whitney Houston, the Isley Brothers, Janet Jackson, Michael Jackson, Rick James, Louis Jordan, Gladys Knight, Patti LaBelle, George Michael (who I'm pretty sure is white and gay), Billy Ocean, The O'Jays, Teddy Pendergrass, Prince, Quincy Jones, Diana Ross, Sade, Luther Vandross, Dina Washington, and Stevie Wonder are "black/race" music. I believe all but two of those actually are black. Take that with a big grain of salt.
Still the original post showed what look like an attempt at Black Gospel Music. That actually is or can be a case where "black music" is maybe an uncontroversial term. There are some denominations of Christianity are predominately African-American or were founded by African Americans.The music of the following churches might fit that.
