Radar to be the 4th single from Blackout/Circus

[womanizer]

Radar is the 4th single from Blackout/Circus

I'm glad it's being released and not Unusual You although I'd rather have Kill The Lights.

I wouldn't bother Kill The Lights following or instead of Radar

I don't know why some fans are shocked, why else would they put it on this album after it being on Blackout and it being the only non-single from Circus performed on tour (I think so anyway).

I knew that's why she added it into Circus!
I think i'd prefer unusual you
