In the age of DJ Khaled and Snapchat celebs, “Mr. Worldwide” is like a versatile old-school showman. Here, Pitbull brings on Robin Thicke, Aerosmith’s Joe Perry and Blink 182 drummer Travis Barker for “Bad Man,” which is like U2’s “Desire” as Miami club thunder, and gives the Soup Dragons’ rave-pop classic “I’m Free” a reggaeton tint on “Freedom.” The guy who promises to “pull a little hair/smack a little oooh” on “Educate” may not always be as charming as his one-world groove, but he knows how to host a party.
