How much do you listen?

After reeading the "how much does it cost?" thread, I began to wonder about the amount of pleasure these systems provide. As far as quantity goes, how many hours a week would you say you are listening to music? With the level of investment in these systems, I guess I'm thinking REALLY listening, not just background music while you wander around the house, but sitting where you can appreciate that you have a 5 or 6 figure instead of a 3 figure system. Please reply in the subject line so it's easier to tabulate later. Thanks!
