How do I get in contact with Nas?

I want to show him this:

http://www.last.fm/group/Nas+Discography+with+Unreleased+Material

I was wondering if all of the tracks listed is complete

I can't post on his myspace for some reason..
for the sites like facebook, I'm pretty sure someone else manages all
of that.
for all the other sites, my message gets pushed to the bottom because
of all the other people posting
