From what I'm seeing, there are no claims that say it does not sound like Hot Hot Hot:
'We regret to inform you that Pitbull has once again been rifling through his Ultimate 80s Summer Hits playlist. This time the wheel of summertune stops on Arrow’s Hot Hot Hot (you know it, it’s the one that goes “hot hot hot”), except Pitbull changes “hot hot hot” to “free free free” so let this put to an end any debates that still rage over Pitbull’s genius.'
Most of his hits are just repackaged tunes. In a way it's brilliant... He somehow captures nostalgia as well as a short attention span at the exact same time. The formula is super simple: Familiar Melody or Pattern + Simple Lyrics = Hit Record
Just grabbed the video. Fun song and a really obvious infomercial for his annual Caribbean cruise and a brand of vodka. There's a rift or two that reminds me of Richie's "All Night Long" but other than that I consider a cover of Hot Hot Hot.
