Seperating Good Mc's from Bad ( wack rapper)

I think A lot of People don't realize what makes a MC good, great , legendary etc. Why a dude like Soulja boy or Bow wow who has sold alot of records, has a lot of fans & continually makes money doesn't get respected like a rapper like Kanye or Jayz or Lil Wayne. Which is funny I'm mentioning lil Wayne as a rapper that gets respect when early in his career he wasn't respected as such. Anyway Ill tell you why he & others are respected.
People get it twisted. They think its b/c rappers like Jayz or Fabolous got street cred or real money & they talk about guns etc.. NO!
That maybe why hustlers & dudes in the streets respect them. They can look at the rappers history & it matches up with the lyrics so yes they respect them on that level. However thats not why they respect them as rappers.
They respect them as rappers b/c  of the lyrical artistry within the rhymes. A respected rapper is respected b/c his lyrics are so different & so well crafted & created from the Average person. Anybody can rhyme words.
Cat hat fat that-- Its not hard lol. What earns respect is when to Quote Nas "I never sleep cuz sleep is the cousin of death"  That stands out so dramatically to people. For an MC to see something as simple as sleep & see the correlation between death & rest & then format that into a rhyme  that makes you analyze & perhaps change your perception on what you're hearing that's prolific.
 To quote Kanye,  " So Much head I woke up to sleep hollow"  A lil more crude but the artistic way & use of word play to describe something as human & every one can relate to as Oral sex is a gift.  To take metaphors ,amp; similes & satire  & incorporate that into a verse where you're also rhyming the words is what makes an Mc great & respected for his Lyrics.
That's why Eminem is respected. he rarely talks about street life or what people consider the Gangsta thug life. Yet he's respected as a rapper. The reason is b/c his lyrics & flow are sculpted like an artist would create a beautiful woman out of marble.  Its so different from the way the average person would rap.
I don't  have anything against artist like Soulja boy or Bow wow personally. If the question was are they good Rap artist I would say yes. They're making money , selling records & they have a great fan base.
But are they respected rappers b/c they're lyrics are prolific or so creatively amazing? NO!!
A rapper who can take words & structure them within bars  that created verses & then say these words with a flow that goes perfectly with a beat & rhythm That's incredible.  But then to add that the words they use  utilize all the literary techniques like Metaphors allegory's etc & make you Think figure out & become mentally invested in trying to solve the lyrical puzzles that the MC is saying. That's what gets the respect.
