So I listened to 7734 (due to Mr. Knickerbocker's recommendation) and Dream Destroyer (due to Mosh). The former is decent and has a solid chorus with Joakim totally not stretching his voice by any means, and the latter has the same Eastern-influenced guitar fill that almost every song on Primo Victoria uses, so it's OK in my book.
There are very few other highlights to this album. I love the neoclassical instrumental section in the title track, though, and the second solo sounds like Mega Man, so I couldn't vote for it. Endless Nights is a cool song, too. I mean, pretty much every song here is lame compared to even their weakest songs from other albums, but still.
Lyrics are generally the least important part of a song to me, but I just can't take the metal cliches. Sure, war lyrics are really a metal cliche, too, but Sabaton excels at that kind of thing.
