3121 is powerful, except for Satisfied. Let's recall some of the old power punches. Intense rock guitar has been proclaimed in the piece called Fury, though its intensity does not rival Temptation, around the world in a day, or Endorphine Machine and Shh from Gold Experience, I could never take the place or ur man, sign of the times, or let us not forget, extended version of Let's Go Crazy, purple rain, or even Darling Niki. The only way to get punch from Fury is to turn it up really really loud. The mentioned collection of Prince is Prince at his MOST intense with the hammer. I'm sure I missed a few. What do ya'll think?
