I must say, I haven't played the songs since a few days after the release, I don't know if that is a sign, but it doesn't grabs me like a lot of Pitbull songs and the majorty of Shakira's stuff, it's a nice song and all but idk.
Latin audience does not count for the Hot 100 right?

Track Review: Pitbull feat. Shakira, 'Get It Started'
Following the success of the "Men in Black 3" soundtrack single "Back In Time," club-rap hit-maker Pitbull figures to have even more songs ruling charts this summer. For the opening single from his upcoming album "Global Warming," Pitbull enlists help from fellow Latin pop superstar Shakira to drive the chorus of "Get It Started." The track is what Pitbull fans have come to expect from their prolific singer: pulsating buildups, pumping bass, and plenty of lyrical allusions to Pit's humble beginnings and glamorous, jet-setting lifestyle ("Only ball I drop: New Years, Times Square!"). There's a bit of a cut-and-paste feel to the exchange between Pitbull and Shakira, although one gets the notion that the two musicians could conjure more chemistry in a live setting. Shakira steals the show here, lending her majestic vocals to a refrain that figures to be heard around the world.
