I like having having a nicely labeled CD with the tray papers.
So do I. I participate in another music forum in which the majority of members post rhapsodic about "the smell, the feel, the look" of vinyl. Much is made of vinyl's superior artwork and packaging. I, however, have always preferred CDs and their packaging from a collecting standpoint. I like the way the cases open up, I like plucking the little silver discs off the spokes, I like placing them in the drawer and pushing "Play," and I like sitting down, listening to the first track while I look at the booklet.
I like the way the CDs look on my shelves. I even have a ruler I use to align the cases. As collectibles go, CDs wipe the floor with LPs, IMO.
Otherwise, if I'm downloading and burning myself, the disc will probably just get lost, and the files will probably get destroyed in a disk crash.
I have a bunch of discs I've burned, or ripped, or whatever it's called, but, yes, they get lost, and I don't feel like wasting the time or money to buy one of those books to store them in.
Also, unless something's otherwise impossible to listen to (the original SMILE, by the Beach Boys; an OOP version of the Left Banke's only album), I don't feel like playing CD-Rs. Finally, yes, if what happened to my old computer is any predictor, the music files on it are going to die someday, whereas my CDs (and the few LPs I have left) have lasted for decades.
