Lol. It's funny how P&W music is hot right now and barely any of it you'll hear in church!
Here are some suggestions
Motor City Mass Choir
Shekinah Glory Ministries
Brooklyn Tabernacle Choir3
Martha Munizzi
Alvin Slaughter
Mary Alessi (from what I heard she doesn't have a lot of original material. However she might have a version of something you might like)
Vicki Yohe (personally I like her version of "Because of Who You Are over Martha's)
Kirk Franklin's earlier stuff
Donnie McClurkin
Look into worship CDs like:
"Together In Worship" - Deitrick Haddon Presents Voices of Unity
"Worship With Natalie Grant And Friends" - Natalie Grant
pretty much worship compilations. Natalie and Alvin sing the version of "Holy, Holy, Holy" that we sing at church. I've heard a few songs I like off of both of these albums that I think are decent. As always, youtube the songs before you buy them.
Songs that we sing on a regular at my church:
You Are Holy - Motor City Mass Choir
He Reigns (We Sing Praises) - Based on Brooklyn Tabernacle Choir's version
Holy, Holy, Holy - Based on Alvin Slaughter's version
We've Come This Far by Faith - Donnie McClurkin
Let it Rise - Based on William Murphy's version
I Love You Lord/We Exalt Thee - ???
Hallelujah - Based on Andre Crouch's version
Hallelujah, Salvation, and Glory - ???
Lol, my mind just went blank on songs we've done!
If I remember the rest of the list I'll get back to you.
