On some maps like dejima a precise weapon could be very reliable as well. For example the AK47 or the KH417. I tried both and right now i prefer the KH417, because that gun has the khi sights i like and AK not. Those guns are slow, but precise. So if that fits your playstyle this is a suggestion from me, especially for maps with long distances.
Opeth - Burden Progressive rock/metal with both clear vocals and grouls in turns.
Scale the Summit - The Leviated This is my favourite progressive rock (instrumental) rock band and one of my favourite tracks from that album (my favourite album from them, all tracks are worth)
Beelzefuzz - Siren’s song(i didn’t found the single track only the full album, just skip to the track called "Siren’s song" at 11:39, because embedded videos automatically seem to have disabled timecodes) The awesome thing about this band is that they do Doom with clear(!) voices.
Macbeth - Gladiator(again i didn’t found the single track only the full album, just skip to the track called "Gladiator" at 24:51) Macbeth is a bit similar to Rammstein. They address different things, they do mostly anti-war songs, but some other issues and topics as well, for example Gladiator-ism, cannibalism and others. They might sound harsh (and epic) because of the german language
