Geez ... they sure don't make it easy. I figured I could post a review stating that the app is a fake, so I signed up with a throw-away email address, logging in, and tried to create a review. I was denied since I hadn't downloaded the app. And I couldn't download the app because I need to do it from my windows phone. Which of course, I don't have.
If there are any windows phone users out there, perhaps they can download the app, post a review stating that the app is a fake and provide a link to the real (and only) MusicBee. And then delete the app from your phone. Caveat emptor: the app may not only be fake, it may be some sort of trojan app, so if you do download it for the sake of posting that it's a fake, you do so at your own risk.
