If we're talking radio stations that broadcast within the borders of Rhode Island...
95.5 WBRU--which I agree with Sky that it's currently the best music station in RI, even though they always seem to be running 5-10 minutes behind schedule. But I don't mind the 9 O'Clock News starting at 9:10.
102.7 WRNI--Gotta have NPR on, and I'm liking that WRNI seems to be gaining presence in the state.
If we're talking all radio stations--
102.7 WEQX/Manchester, VT--Best alternative station, hands down.
88.9 WERS/Boston. Emerson College eclectic-rock station.
