No, I don't use and never used baby powder.

I'm just really curious because I can't find any reference for such thing in the internet and I'm wondering why this happens and I was expecting to get more people to say "yes, I had this problem before", "this is a known problem if you play the same CD for a long time", "this is common" or "this is due to this and that".... It seems to me that this is not common at all....
