I think the most famous Polish rap song is called "Scyzoryk" and I think it's by a guy named Liroy, but it seems he changed his name recently. If you google Scyzoryk you get results including a Polish wikipedia page. That said, I don't know if it's "quality" since this is just what I remember from going to grammar school in America with a whole bunch of other Polish kids of immigrants.

But yeah, there you go for Polish hip-hop.

I think there's a decent French rap scene too...Abstrackt Keal Agram is a band that's made it across the ocean. It's been a while since I listened to them, but there album Bad Thriller is pretty interested.

EDIT: I guess Abstrackt Keal Agram is more of like a synth-pop band or synth-hop band...I don't know but the song Et La Nuit s'éternise is pretty much straight hip-hop/rap. Let me know if you have trouble finding it.
