This has been bugging me for the longest time, There is a song that has been on the radio a lot recently, but the rapper in it is british, or some form of european, and all I can say for sure about the lyrics is this: (gradually getting lower) naaaa na-na (gets a bit higher, but still slower lowers) naaa naa. Sorry I don't know more, but I really want to know the name of this song!
