What are your reasons for listening to your favorite emcee or rapper?

I like Wale,Tupac,Nas,Jay-z, Murs,Gza,and last but not least Lupe Fiasco but right now my favorite rapper is Lupe.Im tired of seeing all these rappers that cant even rap even be considered in the same sentence as Tupac or Biggie please listen to the lyrics and try to see how many rappers you run into rapping about the same thing.
