WQXR.

Music The other night I discovered a new classic music station out of New York, WQXR. It's wall to wall music broken only by local news broadcasts on the hour, brief adverts for itself and sponsor notations read by the DJs. 

There's also a connected live stream called New Sounds which seems like twenty-four hour Late Junction which I've been dipping in and out of although it requires a bit more concentration.
