CD ripping is just so simple with the right software. When I sit down to listen to music,if there are any CDs to rip, I do it while listening to other music. It usually takes about 2 minutes to rip a CD, often less but it doesn't matter really as I am doing what I want anyway, which is listening to music.
The advantages of listening to CDs that have been ripped are much more than not having to handle the CD's. All the metadata on a CD, plus the hundred or so custom fields such as personal rating, mood, instruments, vocalist etc makes creating smartlists based on any number of criteria a real good way to find and listen to music that fits the mood, company, etc.
Last night I set up a smartlists of all the music I have imported in the last 6 months that wasn't blues or rock with just a couple mouse clicks from my listening chair. Later when my wife came home I added some of her favorite stuff mixed in with the current list that was randomized, again with a couple mouse clicks without having to leave my recliner.
This type of control is what I find missing with streaming and unless they start to let subscribers use real Media players such as jriver, music bee etc it will always be strapped to their exceedingly dumbed down players that come with whichever stream you want to pay for.
