“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.”
