OK. I saw some so so reviews from people here and other sites. I say it with a Carrie Underwood track and 18 songs....I thought filler heaven! Albums this long really in todays day and age are a bad move. With busy lives you want to keep the attention of the listener. Well I put it on and was pleasantly surprised! They did what KISS, VH and Heart (though they bombed) in going back to there old sound. This really works. And unlike KISS, Aerosmith kicks some ballads in to break it up. Now I think this album is so good that they should have used 10 tracks and held the others for there next release. 18 tracks is hard to listen thru. They could have done without the Joe Perry tracks, use them for your solo albums. But all in all a classic sounding album! Enjoyed!
