Well, having a few radio shows spanning over 20 years spoiled me. You get used to the convenience of being able to pop a CD into a disc player and hitting the track number and pause button, cued up and ready to go. Cuing up vinyl LPs every two minutes for two or three straight hours is a huge pain in the ass, especially when you're also supposed to be going on mic every so often, keeping a log of the songs you're playing, plugging in PSAs, commercials, etc., and still finding time to answer the phone, run to the bathroom, smoke a cigarette, take transmitter readings, whatever. CDs made being a radio DJ a LOT easier. But these days you don't even need to lug your CDs around to do a radio show... all you need is an iPod or two, plug them into the control board and no one will know the difference. Also, playing your precious vinyl on radio station turntables with questionable needle quality (you have no idea how the other jocks on the station are treating these needles, and they may go six months or a year before getting replaced) you often find your records getting worn down a lot sooner than they should be. So anyway, while I saw the convenience of CDs from a radio DJ's point of view (to the point where I would actually prefer bands send CD promos to me instead of vinyl), I can also totally understand why we've reached the end of their lifespan. They're just not necessary anymore when you can purchase 320 kbps MP3s from just about anywhere and burn your own CDs, or put them on your MP3 players or whatever. They've just become the next dinosaur.
