Yea the amount I've left somewhere or lent to people that I've never seen again would number quite a few too but everything is a mouse click away in lossless format these days so care factor zero.
I'm guessing the only CD's that hold much value are limited pressings, the gold disc audiophile stuff etc etc.
*I do look after everything i ever bought on the Yazoo label & other now defunct blues & jazz labels, I'm never gonna find Blind Willie Johnson & the early delta guys on original 78's so I'm glad labels like Yazoo exist.
CD's are great for stuff like cramming a band's entire discography on one easy to carry around, play anywhere format. That's pretty much what I use them for. I doubt I'd have many CD's where I don't already own the stuff on vinyl. And it allows me to preserve the vinyl by playing it on the CD instead.
