Cover art for Der Kommissar lyrics by After the Fire

Volksfrei: I believe it's a reference to "Slippery Slope" theory:

http://en.wikipedia.org/wiki/Slippery_slope

Basically, one event will set in motion a chain of events which will inevitably lead to a catastrophic result. Given that "Der Kommissar" was a popular 'cop' show in Germany in the '70s, and the female character in question is acting rather strange, I think the theme is that of drug use... the 'slippery slope' being that once one starts doing risky things like abusing drugs ('the more you live...') the greater the chance that you'll end up spiralling downwards ('...the faster you will die').

I like the Falco version better as well, but this is a pretty faithful translation, I think.
