An unknown piano melody

I am in need of the help of anyone who knows the polish rap group WWO (whoa, that many!?) and their song "uwazay jak tanczysz" (~"watch how you dance").
It features a piano melody that they played at a new tempo, but originally, the melody has been played on another track by a unknown-to-me artist.
It may be an eastern european artist who played it originally.

I may send samples of the track to anyone who might know about the answer...

Post a link to the clip bro, there's more of a chance that somebody could know it.

Unfortunately, I have no possibility to set the clip online.
Maybe someone else can?
I can only send it via email to people who want to check it out.
Damn, the melody reminds me on some very precious people...

Can you upload it to www.sendspace.com?

It's a free upload service and once it's finished you can get a link to post on here.

If you cant, email it to [email protected] and i'll stick it up for you

Thanks, Spirez!
This is the link to the download of the clip:

I reduced the audio quality before loading it up so no license is broken by posting it.

sounds kinda like that joint on Best of Both Worlds (jay-z and r kelly) "the streets". i know its not the same sample but thats what it kind of sounds like to me.
