Sometimes, you just get blanks in your memory. Maybe you've blanked out on everything Jay-Z and Kanye West ever recorded prior to Watch the Throne. And maybe it's bugging you so much that you're considering not seeing them on tour, for fear of being that one guy or girl in the audience who still doesn't know the words to "99 Problems."

For all two of you who related to that, here's the perfect trailer, running down every Jay and Kanye hit, a few Grammy/album-sales tidbit, and a lot about game-changing. Ah, now you remember! As for the Throne era, that's really only represented by "Otis." Man. They really do want us to forget "H.A.M.," don't they.
