Are you ready to party like it's the Willennium? Will Smith has made a triumphant return to music by rapping on a remix to Bomba Estéreo's "Fiesta." The song is fun . . . then Will freakin' Smith comes in with his smooth, old-school sound and nails it. Listen, I'm not going to sit here and say lyrics like "Hola mamacita, go get me a beer-a" are revolutionary, but they're more entertaining than After Earth. (Sorry, Will.) Next to a Fresh Prince of Bel-Air reunion, this is the best gift he could have given us.
