I love the fact that about 10 years ago I was listening to the radio, a radio is that thing that plays music between the ads, the station beeped out "high" from "getting high" and "bitch" from a Pink song. The same station played the song "Bitch" numerous times, no issues at all!
Never try to figure out stupid censorship.
Contradictions in song censorship are actually quite common. The reason is because the stations don't do the censoring themselves. They get copies of songs/albums from the studios. Some studios censor and others don't.
This is even more true now that stations are switching to digital media for their music.
