The song, "Equalibrium", is the most mesmerising song I've ever heard. The high and low pitched lyrics are complimentary, and give the song a touch of femininity and masculinity, a balance that allows the song to represent both sexes. The complimentary aspect of the vocals and the guitar ryths associated to them is quite clever: gentle, high-pitched guitar ryths for the man and harder, disorted ryths for the lady during the chorus.
All in all, I'd have to say it's the best sounding song I've ever heard. I enjoy listening to it everyday.
