Different overture results

[jivan]

Hi,

I've get these results using overture Keyword Selector Tool (http://inventory.overture.com/d/searchinventory/suggestion/):
[US market]

american antique auction

September: over 52000
October: 281

download mp3 music

September: over 2130000
October: 14997

How is possibile this big difference?

For other search terms there is a difference but it's little.
Thanks for any suggestion.

Regards
Massimiliano
