This 2 disc edition is an excellent buy if you are a Katy Perry fan.
The songs are essentially the same, however, the sleeve is really good and the bonus disc is pretty good as well as the extra tracks and the remix tracks on their as well.
The whole package comes scented as well, which is highly original and is worth every penny spent as well.
The tracks that standout include California girls, Hummingbird Heartbeat, T.G.I.F, E.T and Pearl as well. The other tracks are also a great mix of sexy and sassy pop music too.
An Excellent pop album, great for young and older adults as well.
