Yeah, great trailer and finally they're revealing some more delicious parts indeed. I also love the dramatic narration voice.
Anyway, for those who are probably curious, mild spoilers which song is which below:
Riff from the very beginning (the one that repeats at 0:18) is from In My Universe, and obviously the chorus from 0:26 too, though it's the first chorus — and the choruses in the song grow progressively more exciting, and it's only a first half of the chorus too. Starting from 0:53 is an amazing driving riff from the second part of Blood of Eden (I love that one); 1:10 is an insight in Godmaker's Temptation chorus, 1:36 onwards (from right before "Netherworld II" is Diabolica Comedia intro, and I can't recall which track comes up at 1:51 (after "now").
This album is seriously awesome. It's in my Top 3 releases this year, and with how many great releases there was... well, you get it.
