I'm also a big fan, still waiting for them to come back on european tour to see them again! My personal favourite is One-X, but I also like the softer ones, like Last to Know.
I think that Life Starts Now (album) had a few filler songs. Songs like Goin' Down, No More and Without You aren't TDG standard. Best album is One-X. Time Of Dying and Never Too Late are my fave songs.
