Remember the good old days, back when we all used to actually buy CDs? I remember all too well: my CD collection meant everything to me as a kid, and I knew the dates of new album releases by heart. More often than not I'd buy CDs just for one song I liked, and I'd give the rest of the songs a chance if I had time. Not so much anymore, though. I think I've bought a total of two in the past five years or so. I'm betting most of you would agree that your trips to the mall for CD purchases have greatly decreased over the years as well.
