Heart plays MJ all the time which I love. I don't listen to it much as I usually whack my IPod so its MJ all day every day but whenever the radio is on MJ gets played a lot. The only thing I hate about it is that they continue to refer to him using the dreaded J word. But in all fairness they don't mean it maliciously.
I have heard Michael Jackson songs on the radio station many times before his death, but I mostly listen to an R&B and Classic soul station so that the reason why I heard it so much on there.
