If you have a radio with a good FM connection, check out the LPFM (no, I don't know what the "LP" stand for) radio station at 87.5FM.  We discovered it quite by accident.  You'll find non-stop Jewish music and there's never any talking.  No clue who's doing these broadcasts, but enjoy!  And at work, don't forget http://www.fivetownsradio.com and http://www.nachumsegal.com for 24/6 audio streams.
Have a great day!
