If you like liberal biased, cont looped 16 hours of NPR and BBC daily then Kjzz is for you.
If you like the 4 hours of Jazz Ration they give you nightly then def worth a listen.
In terms of a jazz station, it's sad.
Other major cities with public NPR stations give you much more jazz and just do NPR updates at the top and bottom of the hour.
Guess in KJZZ eyes, people don't like jazz during the day?
