I think you have a right to be mad at him. The fact that he purposely looks for message boards and chat rooms that you might post in just so he can lurk there and see what you're saying is creepy. Why doesn't he just talk to you about stuff instead of trying to find the information second hand?
Okay- I just checked the number of mp3s I have and it's 4,428! :eek:
Needless to say, I have much less music on CD, although a lot of my mp3s have been ripped from my or my parents' CDs.
