Human: How did the new mix of "Knock Me Down" emphasize Frusciante's voice instead of Kiedis'? Assistant: 
The new mix of "Knock Me Down" emphasized Frusciante's voice instead of Kiedis' because the original version of the song was recorded as a duet between Kiedis and Frusciante. The new mix of the song was remixed before being released as a single, and the new mix inadvertently emphasized Frusciante's voice instead of Kiedis'.
