Why was "Right Round" by: Flo Rida removed from the itunes store?

its a terrible song im glad it was removed but im just curious as to why, i know that sometimes when an artist's album comes out, they take the single off the store, but his album doesn't come out until march 31, also i just checked mtv.com and apparently Flo Rida killed a rabbit in kentucky and is wanted for animal cruelty
