The DFX:
Have you listened to Manowar? How to you?

HD Not Ready:
They have texts in general a weak place, they can safely be divided into four types, and the first three types of songs are virtually no different:

Songs about the true metal and the enemies of the true metal and how they should be wet (early work of manoeuvres)

Songs about the Vikings and Berzers and how they soaked their enemies and how they should soak their enemies - just like they (later work of the maneuver)

Songs in which you can understand what it is about, about the real metal or about the Vikings or the Berzers, but one thing is clear that they are really cool uncles and that they really dohuya missing enemies which must be wet, and the cooler they are wet the better. (creation of the medium period maneuver)

Lyrical songs about military friendship (very little)

There are still a few songs about bikers, but there is also a dohuya of berzerks and enemies of real metal, so this is probably type 3.
