Well, here's a sign of change in the music business: Tower Records is gone:

After a lengthy auction stretching over two days, a federal bankruptcy judge on Friday approved the sale of Sacramento-based Tower Records to Great American Group, which plans to liquidate the music retailer.

I think this is a combination of factors. First, retailers like Target and Wal-Mart started pushing the retail price down. Then, online stores like Amazon made impulse buying easier online. Finally, Apple added the music store, and made instant gratification possible. Left out in the code: old style retailers in thrall to the high prices they had become accustomed to.

On the other hand, I know my wife will miss Tower - she really liked their online store.
