The last time I did a CD count, I was near 350. By now, I'd say I'm around 500 or so.
I still buy CD's from Amazon because they are still extremely cheap and they are just the easiest way for me to get physical music. I distrust itunes or any of that digital stuff. I listen to Pandora, but it only satiates my need and I usually buy the CD from the artists I like anyway.
I can imagine CD's going away for 'newer' artists, but the older bands that release new material will probably always release on physical media. Hell, some artists today release their new music on vinyl.
