Currently, the only stations I know of playing it in my area is the dance station run by a local highschool. But it is an official radio station. They also play some of BoA's US Radio singles.
The first night I heard Dirty Desire play on it, I was at a gas station getting pissy because my BoA cd was skipping like hell. Pulled it out to switch cd's, put in the other cd and said "wait... i know that song....." pulled it back out and realized what it was and started seriously freaking out lol.
