I want to know the answer to the following question:
Along with Trey Songz, Patti LaBelle, Toni Braxton, Whitney Houston, Aretha Franklin, Frank Ocean, Craig David and Mariah Carey, who is a well-known urban AC artist?
All the background I'm provided with is that "The urban AC stations resemble soft AC rather than hot AC; they play predominantly R&B and soul music with little hip-hop.". Is that enough to answer the question?
Answer: no
