I probably should have prefaced this thread before starting it, (I just didn't have the time that morning);
Most or all of the stations I'll post are either community and/or college based radio.
Which means, if one is not familiar with those, from the listeners point of view one can be groove'n on the stream one minute and the next you can go WTF? who would even make that noise or wondering who cares?
Change the channel.
But all of them have programs segments. Pick whatever suit the mood.

When I started this post they were playing some very nice jazz.
