Sometimes upgrading or replacing something can expose deficiencies in one's own processes.
Last week, my four-year-old MP3 player died. It's pretty sad, actually. It's tiny (20 GB) hard disk just stopped spinning. So, not wanting to hear every background conversation of everyone in my client's office, I decided to replace it.
After much evaluation I chose the Apple iPod Classic 120. Then I fired up iTunes and sync'd up my library.
It turns out, that phase in the late 1990s when I ripped all of my CDs in Microsoft .wma format—not such a good idea ten years later. It also turns out, all those CDs I ripped at 64 kHz to save space—the new iPod has good-enough sound reproduction that I can hear it. And another thing, all those album art JPEG images I routinely deleted until about 2005, again to save space—yeah, the new iPod shows album covers, but (duh!) only when they're available.
So, now that terabyte hard drives cost about $150, and I have an iPod with excellent sound reproduction and the ability to show full-color album covers, I have a new project: re-rip all the CDs I ripped before mid-2006, this time at 256 kHz and retaining the album art.
There are only 700 or so. Shouldn't take too long...
