I'm also glad my music is on physical media every time I don't have to pay insane rates for a couple hours of wifi on a flight just to listen to my music, or when I'm killing time somewhere where cell service is spotty at best.
I don't yet live in the future where access to the cloud is a given, and I prefer my devices don't become completely useless without a data connection.
Edit: My primary physical media isn't a pile of CDs—I have plenty of those too, but stopped carrying them the moment I got an MP3 player. Now I carry almost my entire collection on my phone and a whole lot more than that on my laptop. I see nothing wrong with having copies of things in the cloud (remote backup FTW), but I'm not about to take a shotgun to my local disks.
