No one brings it up because it doesn't really mean anything. When you look at the accomplishments of an artist like Jay, that ranks really low on the list, when you look at an artist like DMX it's really high because there's not much else to highlight.
Actually I haven't heard anybody mention it for anyone besides DMX, except for 2Pac here and there. The DMX fans really see at as a big historical achievement, even though it's really a no-brainer to strike while the iron is hot. Even if the result is lackluster work, which is what some on this thread have mentioned (not me).
Either way, it doesn't have to count in your world for it to be a fact. Jay-Z had two #1 albums in one year. I didn't make it up, that much I'm sure we can agree on.
Both of X albums debuted at #1 thats the difference... others have had albums that reached #1
X is also the only rapper to have his first 5 albums debut at #1
Alot of gymnastics and goal post moving to discredit DMX. The original feat is described as 2 albums to debut at #1 in the same year.. anything else is nikkas being extra
