I think the audio quality gives this recording character. What could be more cyberpunk than hearing the quirky artifacts resulting from ripping an obsolete recording medium?
Examples in the following file http://bearcave.com/bookrev/neuromancer/Tape1a.mp3 :
0:40, 1:04, 1:13, 1:21, 2:18 ... I mean.. the files are basically ruined :\
Edit: I read above that these particular MP3s are corrupted, so they have a serious enjoyability issue.
