It's shooting in the dark anyway..
I noticed when you click and hold the scrollbar in safari, the counter stops. It restarts when you release, but you have to refresh to get more up-to-date figures..
The iTunesMS also shows a lower value than apple.com does..
I know when I do my magic click! but I ain't gonna tell anybody... (supersticious..)
Maybe there's a nut going around somewhere who's going to buy 10 000 songs anyway, and just buys a lot of songs at once! ok, it costs him 10 grand, but he get's the 10 ipods for free! (no I am not such a nut...)
