Do you listen to equipment or music.

This Blog got me to thinking about the subject:

In the past I have spent hours listening to the same part of the same song just to fine tune various components of the of the audio system. I even move speakers and listen - move them again and listen more. Sometimes I wonder what I am doing. Whatever it is, when I get into this mode, I am not listening to the music.  It would be nice how the community feels about listening to music or equipment.
