The songs on Twilight in my current order of preference (subject to change with more listens) with comments:
1. Free Will Sacrifice
This song is in the running for my favourite Amon Amarth song period. Lyrically this is definitely my favourite on this album, if you couldn't tell from my sig. As a bass player, I really appreciate Ted's contributions on this one. His playing really adds to the atmosphere and with the kick drum being as low in the mix as it is Ted really manages to keep the bottom prominent with his playing without overwhelming Olavi and Johan's superb riffing. For my money, this song has the best riffs on the album.
2. Twilight of the Thunder God
The opening riff sets the atmosphere. There is no doubting this is an Amon Amarth song from the first notes. Once Johan screams and Fredrik starts pounding the double kick, the whole thing might as well be hardwired to your balls because that's where it grabs you and it doesn't let go. The wankery from CoB's Roope Latvala provides an interesting contrast in an Amon Amarth song, though the brief pinch harmonic intro to his solo sounds more like it belongs in a cheesy power metal piece than here. Since it's only a second long I can overlook it since the song is so damn good.
3. No Fear for the Setting Sun
In coming years, I've no doubt that this song will be considered one of Amon Amarth's classics. This is a really complete song, all of the various elements meshing perfectly into an amazing whole. The solo on this song fits in all the ways that the solo on Guardians of Asgaard fails to.
4. Varyags of Miklagaard
Love the rhythm of the verses in this song. The subject matter puts me in mind of Tim Sevrin's "Odin's Son" trilogy of historical novels, one of which follows the main character through a period of service in the Varangian Guard. A strong opening riff for a mid tempo tale of Viking honour sets the atmosphere and the song remains strong throughout. One of the highlights of the album.
5. The Hero
A really good song that bogs down a little towards the end lyrically. As much as I love the lyrics of the chorus, they just get repeated too much for my taste at the end of the song. Overall, one of my favourites on the album.
6. Where Is Your God
This song is a serious ass-kicker. Relentless. Punishing. The Asator comparisons are warranted, though I don't think this is quite as strong a song overall. A perfect song for being pissed off too.
7. Live for the Kill
Amazing riffs. Musically I think this is the strongest song on the album. Unfortunately, I've always had a strong dislike of call-and-response type vocals like this song features on the verses. As good as the music is on this one, the vocal style on the verses detract from it too much for me to really like it. Great solo and Apocalyptica's contribution couldn't fit the song any better than it does.
8. Guardians of Asgaard
I really, really want to love this song. I love the subject matter. I love the riffs. As a whole, however, this song leaves me flat. The lyrics are repetitive and a little cheesy at points (though I love the "Three evil giants of the south" line) and the solo seems completely out of place. It just doesn't fit the rest of the song. Lar's guest vocals fit well enough. That being said, I'm really looking forward to this one live. This should be a real ball breaker on stage.
9. Tattered Banners and Bloody Flags
Another mid tempo tune that is not as interesting as the one before. I don't have much to say about this one other than it fails to hold my interest. Not a bad song, just not as strong as many others on the album.
10. Embrace of the Endless Ocean
Lyrically one of the strongest songs on the album. Musically, I find this song uninteresting. Like Tattered Banners, it fails to hold my interest. Again, not a bad song, just not as strong as the rest of the album.
On the whole, I think this album is as strong as With Oden on Our Side musically. Johan's vocals are stellar, the production is excellent, and the riffs are relentless. The guest musicians are interesting and provide an additional dimension without seeming out of place, but I wouldn't want a steady diet of them on future albums. Lyrically, I don't think this is Amon Amarth's strongest album, though there are some shining moments.
Twilight of the Thunder God is going to be duking it out with their last three albums for primacy in my CD player. As much as I enjoy the music on their earlier albums, the maturing of Johan's vocals leads me to prefer from Versus the World on.
Of course, all of this is one man's opinion. Everyone else will have their own.
