John's right.
Until we start doing something, Z-100 will be the only "dance" source in New York. And since artists such as DHT and Cascada are established (thanks to John and the gang at Robbins), that's probably the ONLY way dance music will ever BE heard on a Z-100, someone that is WELL known (people DO remember "Listen To Your Heart")
And Z-100 is nothing near a Z-103.5 in Toronto, nor a K-104 in Poughkeepsie, the latter two being dance friendly CHR's.
