The album itself I can only recommend. In a pinch, the tracks heard on Youtube or Amazon right here at trial and then decide, and I've done that.
The bonus material is also worth. The DVD includes the two video clips of Love Takes Over and Sexy Bitch and the making-off of the two video's and 4 other versions of Sexy Bitch, and a 19 minute documentary about the album. On the bonus CD also some good remixes are included.
I can only recommend it =)
