I bought that CD and Megadeth's new CD the same day. I also bought Anthrax's new release on CD and vinyl.

While mp3's are the most convenient format to listen to music, it's not the best for quality. You can own a file, but you can't touch it. You could show someone your mp3 music collection by logging on to your computer and showing them all the files you own, but it wouldn't be very impressive.
