Errors.

I have the Pro Version but it still has bugs: 1. A lot of music genres that were previously there have disappeared, and it only shows three. 2. The quality of the songs go up and down when you change tracks. 3. Some songs take a long time to play, or they don't play at all. 4. The back button, on my cell phone, does not work in certain menus of the app. I hope they keep working on bug fixes, since they are paying for it.
