2009's All World 2 duplicates four songs compiled on1996's All World: Greatest Hits. It’s an acceptable starting point if you don’t need the likes of “I Need a Beat,” “I’m Bad,” “Going Back to Cali,” “The Boomin’ System,” and “Mama Said Knock You Out.” If you already own the first All World, you’ll be getting a disc that adds 13 LL Cool J songs to your collection -- a mix of deep album cuts, minor hits, and major smashes released across the full span of Mr. Smith's career.
