I listened to The Edge of the World, and it's a solid song. It's catchy and epic, and probably the best (and deepest) song I've heard Dragonforce do. I do not like their singer, although he's not awful or anything - I just don't like the quality of his voice. Not enough depth for me.
There's a tonality in the main "riff" that goes in an almost major direction that I didn't expect it to, which is cool. The clean section comes out of left field, and I like that. It has this ethereal quality about it. Very tasteful bass, and guitar as well. I once again must say that this song is as deep as the Mariana Trench compared to the typical tidal pools of Dragonforce I've heard in the past.
Oh boy, are those growls? Processed vocals? I don't think it fits here. I love the synth part that follows, though. The guitar solo that starts at 7:42 sounds like someone fired that gun from Ghostbusters. Hauntingly cool tone.
I was surprised by this tune, as I've only known the "making Mario coin sounds on guitar" Dragonforce. I don't think their singer has the voice to convey this song's emotion properly, though. I'm imaging Russell Allen singing this song and in that regard I'm loving it.
