NEW YORK (AP) — The rapper K'Naan is upset that Republican presidential candidate Mitt Romney used his song "Wavin' Flag" during his Florida primary victory speech, and is seeking legal action as a result.In a statement released Wednesday, K'naan says Romney's campaign did not seek approval to use the song and that he would not have granted permission if it had.The Somali-born, Canadian-based rapper says he would happily grant President Barack Obama's campaign the use of the song."Wavin' Flag" was an international hit for K'Naan in 2010. The song had several country-specific remixes, featuring artists from those territories. It was co-written and co-produced by Bruno Mars' production team, The Smeezingtons.K'Naan says he wants to make sure Romney does not use his song again.
