I would think that "Kill the Lights" would be the more radio friendly song that people would love, but I am in love with "Unusual You" so hopefully it could be a successful 4th single.
I call BS! There has been a lot of speculation about what the 4th single from Circus will be, but nothing, I repeat nothing has been confirmed or announced. So until you hear it from us, take it with a grain of salt, k? We're all still very focused on and excited about "If U Seek Amy"! Meantime, vote for what YOU think the next single should be. xx♥
