Thirteen unreleased tracks by rapper Nas have been posted on the Internet as
MP3 files, apparently without permission. A representative from Columbia Records, for
whom Nas records, could not confirm whether the songs -- which include "Hardest Thing
to Do Is Stay Alive," "Dr. Knockboots Dos and Don'ts" and "Poppa Was a Player" -- are
from Nas' forthcoming album I Am ... The Autobiography. The disc is due out
March 30.
