If you’re like me, you spend your weekends in a hammock listening to conscious rap while reading Scientific American.

So when rapper Nas released his new album, “Untitled,” after much controversy surrounding its previous title, “Nigger,” I naturally did what anyone else would do: I tallied the number of N-words Nas has dropped in each of his albums, and charted the results for your viewing pleasure.

Above: The number of N-words appearing in each album, in reverse chronological order, with “Untitled” being the most recent.

As you can tell, Nas’s use of the N-bomb has followed a notable trend over the years. Clearly, he had some things to get off his chest towards the beginning of his career, after which his use of the N-word has trended downwards in a cyclical pattern.

Statistically speaking, if Nas were to continue recording albums for the next 10 years from now, it looks like he’d average about 60 N-words per album.

(For math geeks: the lim_{t -> ∞}= 60 )

Now, some albums had more songs than others, thereby potentially skewing the true frequency of N-word use. As a result, I’ve gone ahead and divided the number of N-words in each album by the number of songs in that album, providing a relative per-song average of N-word usage in an album.

Here are those results:

The two songs that had the most N-words were “Quiet Niggas” (N-Word Count: 72) and “God Love Us” (N-Word Count: 37), which both appeared on Nas’s fourth album, “Nastradamus.”

So it turns out “Untitled,” which had stirred up so much controversy over his use of that word, is actually one of the least N-word-laden albums in his career.
