I have about 7 MXPX albums, and I have to say that this one is definitely my fav. The songs are really catchy, and despite all these reviews saying that is more pop than punk, I think the album is really great. It has a more mature sound than the older, more "punk" albums and the songs have more variations. The older stuff is good, mind you, but a lot of the songs all sound the same, unlike this album. I also like the fact that these guys are considered Christian rock.. the lyrics are clean and sometimes refer to God and such. All the songs are great, but my favorites have to be "My Life Story", "Buildings Tumble", "Responsibility", "Is the Answer in the Question", "Foolish", "Unsaid", "It's Undeniable", and "Misplaced Memories". Anyway, if you like this album, "Teenage Politics", "Slowly Going the Way of the Buffalo", and "Life and General" are also sweet.
Anyway, bottom line, this album is awesome and is a must-have!
