Why do you think that? (Not asking that in a douche-y way at all)
To me, and I think to most, Untitled show's the band's best form of maturation following Box Car Racer, and shows their strongest musical and lyrical output.
Though I think Mark's best lyrics come on +44
I just prefer them my friend.
They are great sing a long records and a major reason on why I like most of the music I do. I understand people might feel different and that is so cool but for me, I don't rate the self titled as much as I do them. It's a classic Blink sound I love.
