I have a ton of music CD's of all kinds of music - classical, jazz, blues, soul, pop, rock... I think the last ones I purchased were in 2008 and I purchased on Amazon. The last time I moved, I got rid of all the jewel cases and put them in binder sleeves to save space. But aside from some Christmas music, I can't remember the last time I listened to any of them. I thought of transferring them all to digital on my computer and selling the CD's but they are only worth pennies.
With the increased popularity variety of streaming options, I predict DVD's will be the next to go.
Oh and ETA, when my brother bought a new car last year, it didn't have a CD player but does have an iPod and USB jack. The Nissan Sentra I bought also last year still has a CD play, along with all the digital options including Sirrus XM radio, that was supposed to be "free" for 3 months, but nearly a year later, even though I haven't paid anything, it's still on.
