"What I do when I write is that I'll do a raggedy, rough version just to hear the chorus, just to see how much I like the chorus. If it works for me that way when it's raggedy, then I'll know it will just work... Listen to that, that's at home. Janet, Randy, Me... Janet and I are going "Whoo, Whoo... Whoo, Whoo..." I do that same process with every song. It's the melody, it's the melody that's most important, If the melody can sell me, then I'll go to the next step. The idea is to transcribe from what's in your mentality onto tape. If you take a song like "Billie Jean," Where the bass line is the prominent, dominant piece, the protagonist of the song, the main driving riff that you hear, getting the character of the riff to be just the way you want it to be, that takes a lot of time. Listen, you're hearing four basses on there, doing four different personalities, and that's what gives it character, but it takes a lot of work."

Michael Jackson.

"One morning MJ came in with a new song he had written overnight. We called in a guitar player, and Michael sang every note of every chord to him. "here's the first chord first note, second note, third note. Here's the second chord first note, second note, third note", etc., etc. We then witnessed him giving the most heartfelt and profound vocal performance, live in the control room through an SM57.

He would sing us an entire string arrangement, every part. Steve Porcaro once told me he witnessed MJ doing that with the string section in the room. Had it all in his head, harmony and everything. Not just little eight bar loop ideas. he would actually sing the entire arrangement into a micro-cassette recorder complete with stops and fills."

Rob Hoffman, sounds engineer.

 "I normally record a singer about a dozen times before getting enough to mix together a perfect vocal track for an album. With Michael, it only took two to four takes. And one of those takes would be perfect on its own. But hours of preparation preceded recording. We would change lyrics, tempo and pitch, working for days and hours on getting the song just right before finalizing the track. Thriller was recorded and completed in six months."
