Over on JoviTalk, a long time member is claiming to have heard the new album and has written a short review.
Please take this with a pinch of salt. Seb is the guy responsible for www.bonjovi-archives.com which contains the most comprehensive library of Bon Jovi set lists on the net; he knows most of what there is to know about the band, and is generally a valued member of the fan community. He's also a serial trickster who dupes people time and time again with various hoaxes, whether it's fake "play by play" set lists during a concert or fake tour dates. So there's a chance he might be telling the truth but there's every chance he's not. It's an interesting read nonetheless though. :P
