Kanye's most impressive digital opens were for "Love Lockdown", which got 213k in 4 days. "Heartless" 201k. Mind you, both Pop songs. His most recent debuts have achieved him debuts outside the Top 10. Jay-Z's most impressive is "Empire State Of Mind", which did 205k in a week. Don't have "Run This Town" figures, but it has only sold 2 million copies.
And just from general knowledge, they both don't have much a digital pull. That's more of Lil' Wayne's area.
