One of my favorite things about living in Nashville (and Memphis while I was living there) is listening to the amazing AM soul stations.
Soul music just sounds better over AM, especially if you're driving around in the south. The music just hangs heavy in the air down here.
WVOL, the "Mighty 1-4-7" which apparently used to use the tagline "the blackest spot on the dial" is Nashville's AM soul music station. They have a webfeed if y'all wanna check it out http://www.wvol1470.com/ They play an amazing mix of some more obscure 70s funk, 60s soul, 70s r&b with some blue eyed soul and office rock mixed in to blow your mind.
Memphis is home to WDIA and it's 50,000 watts of goodwill. This station was the first station in the nation to have an entirely black crew of on-air personalities. Rufus Thomas, BB King both got their start here. Here's a link that'll take ya to a cool multimedia presentation of the station's history: http://www.am1070wdia.com/cc-common/ondemand/
These stations are voices of their communities and I love it when I can turn off WVOL, get out of the car and go into a meat and three, and here the end of the song I was listening to in the car. I guess that's one thing I love about community based stations like that- they seem to create somekind of living connection that is missing from the virtual communities of today.
