Wow - this album is great. I can usually listen to anything Bon Jovi and I found myself listening to this album all day at work (and still am). Nearly every single song is good and each has a great hook.
It's too hard to pick the best song because they're all good, but if I had to pick one, it's Just Older. In fact I wish Bon Jovi had released this one instead of It's My Life. But even songs like Two-Story Town and She's A Mystery are great.
