I've been using my iPod mini since I received this Christmas and I truly enjoy it. I've heard all the talk about it's battery and I have a quick question. Is it normal for the battery meter to go down a little segment after only listening to a few songs on medium volume? Yesterday morning I starting listening to it after being fully charged the night before and I was a little paranoid about the battery meter already going down after a couple songs. Is this normal, or am I just paranoid?
