I'm not really into the whole MP-3 player thing. I do have an i-Pod, but that's only because my sister wanted a new one and I bought her old one. In the year I've had it I have not added one song to it. My sister and I have similar taste in music, so I just keep playing the same songs she put on it. I have no idea what would happen if I plugged it into my computer. Would I lose all that is on it? I'm not in any hurry to find out. Maybe someday I'll want a new song enough to try it.
