First one is Magic Piano
I read the reviews before buying obviously so I decided to try it. Glad I did it's one of the best music apps on the app store you can play, preloaded songs also play with other people around the world. Amazing
I also purchased Real Racing HD and wow I was blown away, it's hard at first but after a few go's you get used to it. You can also enter leagues and also create games with other iPad users by you which is brilliant.
Anyone not got any of those games try them you won't regret it.
