Hate the word but agree completely that "swag" is a necessary part of being a quality MC. If you don't have it or lose it, your lyrics can still be tight but it just ain't the same...

Common is my example. On a song like "No Competition" or "Hungy" he had dope lyrics AND swag.

In a lot of his later works, he still got tons of lyrics but the swag is gone and it's noticeable.
