Yeah, the headphone to mic is the problem. You are sending only a fraction of the data through the headphone jack. It has been sanitized, restructured, reduced or throttled to make the listening experience work without interruptions (a critical experiential factor).
To record that will give you a bunch of mud. In order to record perfect audio, you have to work with the audio data itself, and not rely on output from programs which are (sincerely) working toward other goals than perfect digital reproduction.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
