"Whistle" Flo Rida

You almost have to feel bad for Flo Rida. Despite two multiplatinum-selling top ten hits in the past few months, his fourth studio album, Only One Rida (Part 2), remains shelved with no release date in sight. Now comes yet another new single, "Whistle." Opening on a distinctive acoustic guitar and whistling intro, the song confirms the Florida rapper is one of the new millennium's most reliable progenitors of great hooks. And with its low-key party vibe and idiotically catchy central double entendre ("Can you blow my whistle baby?"), it's got all the ingredients of the perfect summer smash. So expect to see audiences gobbling "Whistle" up in the coming months—just as Flo Rida's label continues to debate whether or not to finally drop his inevitable future flop. B+
