I always wondered if there were subliminals aimed at each other on records between these two! I am convinced LL made a subliminal diss to Jay Z in response to Jay's line on Encore: 
 
Jay-Z - "Who you gone find doper than him/with no pen just draw off inspiration" 
 
It's on his track with Freeway called 'What You Want' 
 
LL - "I use a pen but there's still never been better." 
 
What do you think?  Its common knowledge that Jay doesn't write any of his lyrics down.  I dunno it made me think..maybe I'm reaching!
