Mp3 What?

I’ve really been enjoying the new Jack Johnson, On and On. What do you call an album (vinyl) or CD when you purchase it via the Internet as MP3’s? An Mp3 group? An Mp3 album? I feel old when I call them albums now, and have attempted to remove that term from my vocabulary. An Mp3 distro? Naw, too Linuxish and geeky. Hmmm, I really don’t know what to call them. You?
