WNYC a&f -by far. Intelligent talk. No "great Americans" idiot-ideology. No commercials. Runners-up are WNYE for BBC and other NPR-PRI talk shows not carried on WNYC. WFUV for music. WQXR for Classical. And, occasionally WBAI. That last one has tremendous potential, but its internal discord cripples it.
The only commercial stations worth bothering with are WCBS-a All news. WINS -All news and WBBR for financial news and interesting capitalist perspectives. These stations are loaded-down with commercials, but if you can plow through that garbage, they still have some useful information.
With the exception of WNYC, for music you are much better-off "rolling your own". Constricted, burned out playlists, mediocre "artists" and loads of commercials are what await you with the commercial music offerings.
