i have to tell you as much as i loved radar when Blackout came out i didn't love it when it was on circus. what is the point of putting an old song on a new album, and now its a single. i should have been a single for the blackout era not this era. i really wanted unusual you, but any song that was on circus would have done and i don't count radar as a song from circus. i'm also not gonna buy radar when the single comes out as i'm sure a lot of people won't because i alread have the song infacti have 3 of them from the albums. i also think it was a mistake to choose another dance song as a single.even though i love britney i'm really disapointed in this choice.
