"Reise Reise" by Rammstein, album: Reise, Reise (2004)

Auf den Wellen wird gefochten,
wo Fisch und Fleisch zur See geflochten,
der eine sticht die Lanz' im Meer,
der andr'e wirft sie in das Meer

Ah, Ahoi

Reise, Reise,
Seemann, reise,
jeder tut's auf seine Weise,
der eine stt den Speer zum Mann,
der andere zum Fische dann

Reise, Reise,
Seemann, Reise,
und die Wellen weinen leise,
in ihrem Blute steckt ein Speer,
blutet leise in das Meer

Die Lanze muss im Fleisch ertrinken,
Fisch und Mann zur Tiefe sinken,
wo die schwarze Seele wohnt,
ist kein Licht am Horizont

Ah, Ahoi

Reise, Reise,
Seemann, reise,
jeder tut's auf seine Weise,
der eine stt den Speer zum Mann,
der andere zum Fische dann

Reise, Reise,
Seemann, reise,
und die Wellen weinen leise,
in ihrem Blute steckt ein Speer,
blutet leise in das Meer

Reise, Reise

Reise, Reise,
Seemann, reise,
und die Wellen weinen leise,
in ihrem Herzen steckt ein Speer,
bluten sich am Ufer leer,
bluten sich am Ufer leer

english translation from here:

Even on the waves there is fighting
Where fish and flesh are woven into sea
One stabs the lance while in the army
Another throws it into the ocean

Ahoy

Arise, arise seaman arise
Each does it in his own way
One thrusts the spear into a man
Another then into the fish

Arise, arise seaman arise
And the waves cry softly
In their blood a spear is lodged
They bleed softly into the ocean

The lance must be drowned in flesh
Fish and man sink to the depths
Where the black soul dwells
there is no light on the horizon

Ahoy

Arise, arise seaman arise
Each does it in his own way
One thrusts the spear into a man
Another then into the fish

Arise, arise seaman arise
And the waves cry softly
In their blood a spear is lodged
They bleed softly into the ocean

Arise, arise seaman arise
And the waves cry softly
In their heart a spear is lodged
They bleed themselves dry on the shore

Obscured lyrics, may they have to do with any kind of violence in the sea by humans. But the video clip is quite interesting with footage from the environmental movie "The day after tomorrow". Also the title means Journey and Arise. As we read in wikipedia and in the above site:

The phrase "Reise, Reise" is used by seamen as a wake-up call and finds its roots in the Middle High German verb "risen", which meant "to rise" (to which it is obviously related as well). This verb has since died out in New High German, though the noun was retained and came to mean "journey" or "voyage". The verb "reisen" was rederived from the noun "Reise", but now means "to journey" or "to travel". It seems the old meaning has been preserved in this phrase in the seaman's language.

So hearing the song and seeing the video clip, the song may become an environmental warning too
