With Heart and Voice - Richard Gladwell hosts a wide range of recorded choral and organ music. The syndicated one-hour show is aired on public radio stations around the country - see http://jrabold.net/radio/ for a nifty listing of all webcasts (it even takes care of time zone differences for you!). , From its home base, WXXI in Rochester, NY, the program is two hours, from 8 to 10 am (Eastern time) on Sunday.
Overall audio quality of WXXI's feed is somewhat marginal... it is one of the most extreme cases of excessive audio compression I have heard on classical radio internet streams, with even soft passages brought up to the same volume level as the loudest, with the accompanying audio artifacts. In addition, their audio level is way too low, about 15 dB below the maximum.
Format: mp3, up to 96 kbps
Problems: Severe audio compression, low audio levels
Playlists: Yes (only for national 1-hour version)
