Those stations are programmed better for residents of Australia than any CHR in the US is. That's why those stations are in Australia and Z-100 isn't.
I don't know what your problem is, but... continuing with Z-100 as an example... it is programmed for New York City. It reflects the tastes of the majority of the CHR kind of listeners and together with its sisters WKTU and WWPR they cover the three main currents in hit based young adult music formats in English.
lol, that first sentence is priceless, but rather than resort to that... People can get music anywhere, the stations in Australia use strong personalities not just in morning but in the evening drive time as well, they offer exclusive content in that aspect and would be wise for the chrs hear to bookend their morning shows in the same way. It goes without saying that there are differences between the two countries but down under they do radio better, they give their listeners a superior product than what our listeners are getting here. Take the guy who is running kbig, he has international programming experience and it is highly doubtful that that station would enjoy the success it has now with someone who only knows US programming. It must be a different mentality, from what I hear it is programming by fear too much over here, forgetting that you are entertaining people.
As for the NYC stations, Power 105-1 is just about perfect, the morning show is excellent, Charlamagne(sp?) is very funny and a great entertainer, the music is dead on, and Angie in afternoons is a New York staple. Ktu has been modified to be a flanker against 92-3, the best for ktu would be a hybrid of what they were and what they are now, too much older music before 92-3, but now they don't play enough of the rhythmic gold that made ktu special. As for z100 Elvis has a phenomenal morning show, z is a great station for sure, in my opinion they sounded better about a year ago than they do now, but for an American chr they are about the best you are going to get. They were playing their powers on a 60 minute rotation the last time I listened, I don't think the heritage chr needs to do that. I get the secondary chr running a rotation like that, but I don't think it's right for Z100, 75-90 minutes I believe would be best for them. I'm sure they just do that at certain times and have their reasons. I also have heard them play some questionable songs in middays that weren't and never became hits, it's nitpicking on some level for sure, but isn't that the purpose of a board like this? I don't see it as a problem as you seem to, sorry that some opinions like saying we need a heavy metal station in New York are not easy pins for you to knock down and dismiss.
