Not good

After all buying the full version of it, the company still forcing people to do something for more songs. Some of the jam songs is quite hard to play. Cannot push the notes because they come so fast and near notes so need to use two fingers but not enough place to do so. Also I didnt know the exact number of songs available to jamming but I suppose there is less than 1.000 songs which contradicts the commercial of the program in free version.
