OK, OK. Old Lady here to jump in with her 2 cents.
I remember when 45's were the norm and wow, when we had enough money as kids to buy the entire album, wow that was a lot of music. And then double-albums came out (Jesus Christ Superstar and the Beatles White Album were my first doubles) - wow, it took all evening to listen to every song. And we even had to flip the records over and put one back in the sleeve while we pulled the other one out, blew on it, then smooshed it onto the spindle . . . OK, you get my point.
You can only listen to one music piece at a time, right? Why not have just a few CDs to listen to at a time? I often get obsessed with one CD and that's my main music companion for a month or so, to the exclusion of nearly everything else. Do I listen to every piece on my 2G Nano aevery day? Uh, no.
So Old Lady cheers on those who want only they can reasonably use and enjoy. Go for it.
