Britney Spears Blackout (Pvg)

It is amazing. It is very simple to play yet the songs sound very complete. If you buy this expecting good music sheets your gonna be amazed. Tho, there is one thing that got me a little confused. Some songs are in the wrong key. I don't know if they did it so the songs can be more playable but it does not have a warning or something letting you know the song is in the wrong key or it is half step higher/lower. I usually like to put the song on my stereo and I would play the piano with the song playing, but because the keys are different, they sound messy. But besides that it is a really good one, and I say buy it!
