The rhyme notebook may be going the way of the buffalo, but writing isn't lost on Nas. The Queens lyricist has a rich history of documenting his writing process, even dedicating an entire song to it, "Book of Rhymes," on 2002's God's Son. Though smartphones have seemingly become the go-to device for anyone who still writes (rather than building rhyme schemes in their heads a la Jay-Z), Nas has continued to make references to his rhyme book. Through he's clearly still writing lines down, no one actually knows if he's traded his notebook for a blackberry. As we cross our fingers hoping Nas hasn't given up on the writing method he's helped romanticize so much, XXL lists some of the most memorable rhyme book references he's made throughout his career.— XXL Staff
