IMO I don't think the Beat nor the Party has anything to worry about. One thing is for sure, the Beat will hold onto its number one slot unless some drastic changes in programming happen there. As far as Sunny and Bayou are concerned, they have two tottally different target audiences. I can't see someone picking one over when they are not on the same format. From what I've listened to 92, they are sounding good and picking up steam. If anyone should be worried about Bayou, then it should be KNOE, the only thing that will help KNOE is the 100kw signal.
Just my thoughts!
