Aside from travel, I've probably done more discretionary spending on used CDs than anything else. There were semesters in college where after I paid my university bill (covering tuition, housing, and food), I spent more money on used CDs than everything else combined. I haven't bought any CDs since March because I don't have a good place to put them, but I'd better head to Barts this week to get good deals on stuff that won't be there if I procrastinated.
I don't know which hurt Barts more: Internet music sales or recession economy. For all that's great about the Internet, I love buying used CDs in funky local establishments a lot more than on my computer. The fact that selection is limited means I won't spend too much money buying everything I can think of. The search process means I find something interesting and get really excited, a much bigger "I'm Feeling Lucky!" experience than typing a few words into iTunes. Plus, CDs are a more robust storage mechanism. I'd have been really bummed if I'd lost thousands of dollars when I dropped my hard drive on the floor, but if I drop one of my boxes while moving stuff out of storage, I'll probably just crack a few jewel cases. Sure, CDs can get scratched and otherwise damaged, but that's only losing eight bucks at a time.
Update 9/28/2010: Apparently Bart is back in business on a small scale. Bart's Music Shack is at 236 Pearl St. And the focus is people like me who love finding an interesting used CD that they wouldn't have thought to download.
