The inherent problem is as follows:

I have observational evidence of people who like the strictest of silence to work. They are unable to concentrate with even the slightest amount of noise in their environment - they are, applying your theory, addicted to silence.

The other problem is that addiction is a difficult study; you can't sync your theory with nicotine or alcohol because those sorts of addictions are metabolic - in that there is an actual physical/chemical addiction.

And, finally, if you are right and music can be addictive - what's the problem? It's entirely non-harmful, no side affects and helps you concentrate. It sounds like the ultimate drug :)

You've constructed a very strange theory :)
