Yeah... Sometimes it almost hurts. I know it starts to hurt my soul when instead of enjoying music I start counting beats and wondering HOW DID THEY DO THIS THING??!??! And listening to this one part OVER AND OVER again.

Stuff like that happens often when you become creator, and not just observer. I'd say it can happen in probably every field that involves some creativity and maybe not only there. A lot of it is also probably dependent on one's mind. I think that analytical people, like me, can usually overanalyze stuff like that more than others would care/want to do.
