Invest Your Time, Don't Spend It

>Listening to music and talk radio helps reduce our rage on the road, but like television is only a mental diversion. Commercial radio will provide no real future benefit in your life.

Surely music has value beyond mental diversion. No sources here but I think music can have a measurable impact on mood and overall quality of life.

Edit: I completely agree about shopping though. I don't want to waste a single second of my life shopping.
