Hybrid Theory - it's the first, and you can't beat it... in my opinion, anyway, followed by Meteora and then MTM. I liked them all, but Minutes comes 3rd because I preffered the old LP formula - Mike rapping, the riffs, and then Chester switing between singing and then screaming the bridges, etc. I know that the sound had to change because nobody wanted a hat trick of the same old thing, but when Qwerty was released, even though it wasn't going to be on the album, I just expected MTM to be heavier than it turned out.
