Two facts: The songs on Jay Z albums that feature Beyoncé suck. The songs on Beyoncé albums that feature Jay Z do not.

"'03 Bonnie & Clyde" (from Jay Z's The Blueprint 2) = sucks
"Hollywood" (from Jay Z's Kingdom Come) = sucks
"Lift Off" (from Watch the Throne) = maybe it doesn't suck but still kinda whatever
"Part II (On the Run)" (from Magna Carta Holy Grail) = sucks

"Crazy in Love" (from Beyoncé's Dangerously in Love) = amazing
"That's How You Like It" (from Beyoncé's Dangerously in Love) = v. underrated
"Deja Vu" (from Beyoncé's B'Day) = transcendent
"Upgrade You" (from Beyoncé's B'Day) = essential
"Drunk in Love" (from Beyoncé's Beyoncé) = basically the new national anthem
