I loved the beginning when it has the low ambient sound in the background while the sounds come flowing in on top of it and it starts to pick up the beat about 40 seconds in. However I disliked it when the music all of a sudden started blaring really loudly around 2:20 with the "guitars?", and around 3:15 I started liking it again but it was too high pitched for me so it hurt my ears a bit. Other than that half of the song that I don't like it was pretty good.
Just on another note though, I am deaf so I perceive sounds differently than other people do so don't take my perception too personally. =)
