Monday saw the debut of the iTunes Music Store. My favorite computer maker has started an online music download store, and I was eager to try it out. The first day I spent five dollars on music, more money than I’ve spent on music in some time. Sure, five dollars isn’t much, but it’s more than I would have spent before. What’s more, I likely will spend even more money that I wouldn’t have spent before. As the hardest working man in show business once said, “I feel good.”
