Note that these are not "urban" stations and they do play lots of material that does not make the Urban charts.
A good comparison is KRRL in LA, which is classified as Urban and KPWR in that market, which is a Rhythmic CHR. Both get over 60% of their listening is from Hispanics and less than 20% is from African Americans... the difference is in the music as a whole.
