50 Cent albums/Mixtapes I can't find for download

I actually can't find a copy of:

50 cent - freestyle b4 paystyle (2007)
50 Cent - Greatest Street Hitz (2002) : musicmp3.ru/artist_50-cent__album_greatest-street-hitz.html#.UnCIBRBGZKp

Let me know if anyone have a copy he can send me or a download link.

Thanks in advance!
