I want to know the answer to the following question:
What style of singing is absent from R&B played on urban adult contemporary format stations?
All the background I'm provided with is that "The urban adult contemporary format (a term coined by Barry Mayo) usually attracts a large number of African Americans and sometimes Caucasian listeners through playing a great deal of R&B (without any form of rapping), gospel music, classic soul and dance music (including disco).". Is that enough to answer the question?
