Well, I was surfing Barnes & Noble's music webpage, and I was typing in various Bay rappers to see if they had any of their stuff in stock. When I typed in "Mac Dre", AL BOO BOO was listed as a title, and the stats said "this product will be released on October 21, 2003. You can pre-order it now and have it shipped to you, etc."
Not sure if that date still stands, though, but that's what B&N's page said...
PEACE!
