Keith or Ricky?

I've had the pleasure of reading some enjoyable biographies - Thomas Jefferson, Bruce Dern, Frank Lloyd Wright, Mike Farrell (MASH), Daniel E. Sickles, Brett Favre, Ricci Martin (Dean's son) Vince Lombardi, Howard Stern, Frank McCourt, Dennis Wilson, The Beach Boys, Abbie Hoffman.

Think I'll pick a music genre. Which autobiography do you think I'll end up buying? Keith Richards or Ricky Martin? Hmmmmmm.....I'm an unpure purist, something like that.
