When I first listened to MTM, it was indeed "different", I was still a teen around that time, so I didn't really "gather" what LP was trying to go for. But, as an adult now in his late 20's, I have to say the album makes A LOT more sense to me than it ever did. From the very first song, Wake to TLTGYA, I feel it tells a story of a person transforming themselves from their "older" self, into a newer version, "seeing the light" so to speak.
Wake = Awoken
Given Up = Gave Up on the old ways, sick of it.
LOATR = Saying goodbye to the old self
Bleed It Out = Talks about death a lot and being buried
Shadow = Leaving, avoiding the doom. The sun will set for you, if you want...
What I've Done = Remembering all the bad done and fixing it
No More Sorrow = Politics, how hypocritical they are (And continue to be)
Valentine's Day = Someone being laid to rest, don't know what to do with oneself.
In Between = Sorry for what you are hearing hurts you.
In Pieces = You told me to move on.
TLTGYA = No one wants to help.
The album, is completely about change of oneself. At least the way I see it. ATS is a whole different monster, and growing up, has become my favorite album to how deep it is. After HT and Meteora, i feel LP were trying to get a message forward. That went into a complete 360 with OML though.
