Since I torrented about 95% of my collection, that's probably true, they do OWN it where as I do not, but still...I'd not want to own 50,000 songs in a "physical" form since I'd need to buy a new house...
Also, CDs get scratched, CD players wear out, start to skip, give random "CD ERROR" errors, don't work when it's too cold or too hot, skip when you're driving over a bump.... all things that digital forms (MP3 player, USB stick) don't suffer from...
It's hard to go back to a car (or even house) with just a CD player and not even an AUX in... makes it feel like we're in the 90s...but apparently it's mostly me.
I imagine all of my colleagues have atleast 30 or 40 CDs (bought and paid for), with the cases AND the booklets cluttering up their car, while I have about 32GB (8.000 songs or around 600 CDs, I did the math) worth of stuff I got while sitting on my ass behind the computer, on something the size of my thumbnail, that's not even visible when it's inside my stereo...plus I can delete everything and put new stuff on it all in about 5-10 minutes...
/end rant here, moar new toys plz
