Rick Rubin reveals the three completely different creative processes used by Eminem, Jay-Z, and Anthony Kiedis "Eminem will always be writing in a book, always writing all the time. I asked him, are all these rhymes used? He's like no, 99% of what I write I'll never use, just to stay engaged in the process of writing" "Jay-Z doesn't write anything down. He listens to the beat, hums, then goes on the mic 20 minutes later and just says a whole complicated verse. No paper, no writing, nothing" "Anthony Kiedis sings along with an idea of a melody but he doesn't yet have words, just nonsense words automatically real time, then listens back and says this phrase sounds good. It's like a puzzle"
