No one's buying music on CD's anymore. DVD-R's have replaced CD-Rs as a storage medium; blu-ray is soon replacing DVD-R's/DVD's.
What are CD-Rs used for now any way? Music play back? Nope, no one walks around with CD-walkman. Even tape walkman was preferrable as it didnt skip or shut off at a slightest bump. iPod/MP3 is the only portable music player. Thus, CD-Rs are going the way of the floppy, zip, syquest, jaz, etc.
Now how about playing music on DVDs or blu-ray?
