Like for instance, my local CHR/Pop station plays the explicit version of Scream & Shout with the **** and bitch, though the song is shortened. Whenever I'm out of town I only hear the Britney, Britney version though. Do your Pop stations play explicit music?
Depends on the radio network. Some are more casual than others. Words like "bitch" and "shit" aren't that big of a deal in Australia to be honest, so it won't be surprising if they don't censor those. During the night programs however, they are far more lenient and don't have to block out things as much.
One night at like 10PM I was driving home and my local pop station was playing We Run The Night. Pitbull's part came on and they played the uncensored part of "now **** you pay me" and I was seriously taken aback it's weird as hell hearing uncensored music on radio. I guess my station does it at night.
I depends. Later at night (like after 9pm, I think) they play explicit lyrics.
EDIT: I remember when "Unfaithful" was on the radio, they edited the word "gun" from the line "I might as well take a gun and put it to his head; get it over with".
