If KIIS has added it will other stations be likely to follow?
Yes. I'm sure they will. Now in Ny Added it last week and it's z100s(#1 station in the US) main rival so they keep an eye on what the other one added so I won't surprised if z100 follows now and adds fancy. Kiis adding it is not surprise since they have been playing it so they might have gotten really good reception when they first played it. Kamp(kiis main competition in LA already added it last week so the smaller station will most likely follow them. I'm requesting here in Dallas (#5 biggest radio market) hoping that out kiss fm adds fancy. Is looking good for our bitch tbh. Having 3 stations from the two biggest markets is huge considering her previous singles struggled to get played.
And she looked gorgeous too
