One thing I really miss is the Used CD market. I know you can still get second hand CDs, but in the bad old days every music store would buy used CDs and sell them for like $7-$14 depending on how popular. In a mid-size town like mine, that'd be half a dozen stores.

I used to go to a music store every Sat and just flip through their used stuff. I'd pick up a CD or two every week and before you know it, I had a collection that's robust enough that I've never created an account with a streaming music service.
