Help Please - Record Uploads, How?

I'm keen to record which files are the most popular uploads from my PC. I use Kazaa and WinMX. Kazaa has a limited log, MinMx better but I'd like to keep the results cumulatively not lose them once i disconnect. Any Ideas?

Before you 'pirates' start complaining, I'm not a network adminstrator or some guy out to check up on others, just an interest to share and record !!

Thanks !
