In the wake of Mike-FM's demise, I'd like to draw attention to Toronto's Boom 97.3, which essentially replaced the Jack station in that market. While classic hits, it leans a bit more toward the new wave era and features longtime market personalities. Great sound and would love to hear something like it in Boston (and yes I love hearing the Canadian content). Check it out.
