A little late to the party here I know but whatever. While I will admit that this song isn't my favourite of these it has one major thing going for it and that's in the vocals.
Not so much the lead vocals, It was the chorus that let the song down a little for me, but rather that... chant/backing vocals that ran behind the guitar riff at the beginning and after each chorus. When those kicked in the song picked up hugely. Not sure if there are actually words there or if it's just noises to fit with the guitars. Either way it was a brilliant addition and helped the song beautifully capture the middle-eastern vibe. An excellent touch there, it really made the song great.
