All the lyrics I have make perfect sense. The lyrics are only horrible and in broken english when you read the bullshit that sites like Darklyrics have... FUCK THE IDIOTS WHO SUBMITTED THOSE SHITTY LYRICS.
The problem with questions like this is that most people don't understand anything about music... and start throwing labels and words around and pretend they know exactkly what they're talking about. Like when somebody said HCD isn't as technical as the other albums. Well, I'm sorry, but Alexi, Janne, and Jaska have never pushed themselves this far in a studio release. Examples: Alexi - end of Hate Crew Deathroll solo (that must be at least 300 bpm, in -sixteenths-! Cause it's at least as fast as that part in the Bitch Is Back (280 bpm))... Janne - Chokehold, obviously, but there are others... Jaska - part before the second chorus in Lil Bloodred (or look at the song HCD, lots of fast stuff)... all of these parts are unbeliveably fast and cool.
My two cents is: I don't care to presume what their next album will be, it'll be good stuff, and that's what matters. Each one gets more technical, that much is obvious... and each one gets more accessible to the general populace. I'm not saying that they sold out or anything, it's just a fact.
I completely disagree with DeadWinterDead... although they use similar elements, song-by-song everything is different, and Alexi has new influences all the time. Like someone else said, when you compare their songs, they are completely different. I've heard ppl (more like musical bigots then ppl) say Everytime I Die is just like Bed of Razors and that Angels Don't Kill is just like Everytime I Die, etc... well, just cause it's the slowest tempo song on the cd doesn't mean it's the same fucking song from album to album. However, this isn't the best example because EID and ADK have almost the exact same lyrical subjects... but with a band like CoB, lyrics aren't terribly important.
People always say Hatebreeder is very thrashy, but I don't see a whole lot of thrash influence. I see more thrashy stuff on HCD, personally... oh well, labels are labels, and everyone's perceptions of labels are different.
