::Being owned by NBC does not automatically confer notability  I'm sure they own all sorts of crap.  I know nothing about the Mun2 website but just glancing at its content does not inspire a lot of confidence in its journalistic integrity.  And that chart specifically looks like something that was just thrown together for the fun of it as opposed to a serious attempt at chronicling the lives of either of those two rappers.  For all we know the information about his name could have been taken from the Wikipedia article (which used this as his name before the Mun2 article).  My feeling is that if this is his real name then there should be another source out there to corroborate that fact, a source that doesn't look quite so sketchy.
