I have the premium. I'm in my first week and very happy. I really like the choice of songs. I also like the way it shows you the key shots of the song/mode by dimming the GI and lighting the mode specific targets when choosing the song. As soon as you shoot the ball, the playfiled lights up as normal. I really like the variety of gadgets and sounds. Bell, Train, TNT, Band, Cannon, lower PF. It has a family mode option and can seperate volume on voice and songs.
Currently, the cannon only scores when shooting one target bank. I'm hoping that opens up in later modes or new software code.
I had a white LED roll down my pf from near the pop bumbers and I have no idea where it came from. So far, I have not regretted it at all. It's a very nice game.
