Music Banter - whats this song ?

hi all new here ! I'm really not sure anyone will have a clue and I am sorry I dont have more info.Yday I had this song in my head all morning really bugging me :banghead:- typically by time I get near a pc I have forgtten the lyrics ! all i do know is it says "witch craft" in lyrics - not title and I think its a man singing about a woman ! lol ! and its in charts been on radio a lot in last 6 months. Now I know that is very little to go on ! but if anyone has a clue I'd be thrilled and I will keep thnking - anyone who gets it gets a big bar of virtual chocolate thanks !
