Flo Rida’s teaming up with 5 other writers and 2 producers (including DJ Frank E) resulted in his 3rd ever number one, after Low and Right Round. Out of them all, the American rapper predicted to Billboard that Whistle “will probably be the biggest”.
The song’s lyrics are a metaphor for oral sex, which split the critics in their opinions. Digital Spy stated that Whistle could be “the most original song Flo Rida has turned out to date”, but felt the metaphor was “anything but [original]”. Pop Dust and Billboard criticized the lyrics as well for their lack of subtlety, the former feeling the metaphor is ruined by being so explicit, while the latter describing Whistle as Flo Rida’s “least subtle single”. The rapper himself commented on that: “Well, put your own swing on it, but for the most part I keep it clean, but if you listen to it, you can take it another way as well.”
Despite this, the song was praised for its catchy nature. Rap-Up singled out the whistled chorus, warning us that we won’t be able to get it out of our heads. Pop Crush described it as “breezy pop rap tune, complete with chilled-out guitar strums and a catchy whistled melody.” In another article, they anticipated that Whistle will be at its most successful during summertime, calling it “a perfect summer song”.
Whistle spent 2 non-consecutive weeks at number one in Billboard Top 100, both times being dethroned by Taylor Swift’s We Are Never Ever Getting Back Together.
