stupid song

i have this stupid song stuck in my head. i heard it yesterday on sirius 1, the top 40 station and this afternoon one line started repeating in my head. its not even that good a song, and i don't know who its by or the name of it. all that repeats is the poor voice of a guy singing, be careful what you wish for, cause you just might get it....
its really getting annoying. i'm not so sure i like my subconcious being so overt lately. i'm not liking life being what it seems... its eerily predictable.
