If you are looking for something more R&Bish (somewhat similar to secular music), then you will love Ramiyah's CD.
They performed at a Single's Conference I attended;they were AWESOME. In other words, I hardly listen to the radio because their CD is on constant repeat. I believe that they performed at the major conference in Atlanta this year, I believe it was Mega Fest.
In terms of a slower, more mellow CD then check out Javen's latest CD, Change. It's truly moving. The entire CD is good.
