The Arizona Republic interviewed Sinbad and take a look at this Q&A:
Q: What would fans be surprised to find on your iPod?
A: I've got three of them, and it runs the gamut. There's always some funk, some jazz fusion, some jazz-funk, some rockers that can really throw down. There's a lot of hip-hop Christian rap on there, too. I don't know if that would surprise people. What would surprise people?
