Well she's not black nor does she have a rapper on every song, so Urban radio won't play the music, and you know that. So there really was no point in you saying that. Same goes for Madonna, and other people who could be supported by Urban radio, but aren't.
"Radar" would do better, its so "Toxic"-like as far as the overall pop sound which radio would love. They're lovin' "Break The Ice" right now, she just needs to do something to make it take off faster than its going. Thats why with a video, performance, something for "Radar" it'd do good. "Toy Soldier" is good, but I'm leaning more towards "Radar".
