WRKO and Wimex were legendary. I also would bring back WBCN any era, WROR in the mid 80s, WHDH in the 70s, and WBZ in the early 60s.
Not one person mentioned WEZE when it was Z-1260 after being beautiful music almost from the beginning.
It was programmed then by Steve Hunter, who came from Drake-formatted CKLW in Detroit and actually lived in the hotel--some said he slept in his office! Alan Colmes did mornings, Neil Cannon did nights, Hunter did a shift, and Chip Hobart worked there. This was circa 1973 when an AM at 1260 with calls like WEZE (and their history) could never hope to get traction. Moreover they station had a short lifespan.
WEZE had that picture window there in Park Square. They always attracted gawkers--high quality gawkers. Being between the bus stations, a block off the Common, and not far from the Combat Zone I imagine there were always two shows going on--the one inside that window and one out there on the street.
Radio could use is a shot of magic these days. Who has street level studios anymore? It seemed like every town of any size had at least one station with a picture window. How many of us fed our dreams freezing our butts off outside some radio station's studios when we were kids?
Anyway...The fact is most of the stations mentioned in this thread wouldn't hold up today because they would skew 50+.
I remember my buddy had a film project to do in High School. We went into Boston and one of the things we filmed was Bill Smith doing his show at the WEZE studios. He stood on his head in the DJ chair for us!!
