Ok first let me say that I am not a very big fan of this band, I liked their first CD, but then the last few were more of radio friendly stuff, that being said I gave this CD a try and it is surprisingly decent.
It sounds to me that the band got a new drummer, or the guy just improved greatly and took some lessons. Also the consensus of reviews that I have read regarding the CD is that Nickelback is "back".
Whatever that means? But I have to admit I really do like it.
