Sinner's Crossroads, hosted by Kevin Nutt.
A program (and podcast) on WFMU, this hour long gospel program features some of the best songs I've ever heard on a regular basis. I can't even delete the podcasts because I listen to them over and over, knowing that I'll probably never be able to track down most of these recordings, even with the power of the internet on my side. Host Nutt does a good job of not getting preachy while on the air, leaving something of a sober look at some of the most excited and uplifting music ever recorded.
If you've ever avoided the genre because of the religious implications, seriously give this a shot. I'm not promising anything you'll like it, but it's worth at least being familiar with.
