It is a scientific image, I believe public domain. Happen to love music and you will find that reading the book. The cover is the first clue. ;)

I guess, but it's lacking the dyadic relationship between the image and the music (or in your case: content).

That's what made that album cover so great.

Are you drunk? You think a data plot has an intimate relationship with music but not software? Sounds like someone is romanticising. ;)
